2002 JEEP GRAND CHEROKEE LIMITED (WJ), ELECTRICAL WIRES MELTING AT BLOWER MOTOR CONTROLLER (RESISTOR BLOCK) FOR HEATER /AC INTERIOR FAN. FIRE HAZARD AS THIS CIRCUIT IS HOT EVEN WHEN THE VEHICLE IS OFF. POOR CONTACT BETWEEN THE WIRE FEMALE SPADE CONNECTOR AND THE BLOWER MOTOR CONTROLLER MALE SPADE TERMINAL CAUSED EXCESSIVE HEAT WHICH RESULTED IN THE WIRES BEING CHARRED AND THE BLOWER MOTOR CONTROLLER HOUSING MELTING. DEVICE IS LOCATED UNDER THE DASHBOARD ON THE PASSENGER SIDE. I AM ORDERING A HARNESS AND HEATER RESISTOR TO REMEDY THIS MANUFACTURER DEFECT. WHILE MY CAR DID NOT CATCH ON FIRE, THIS IS CLEARLY A FIRE HAZARD THAT SHOULD BE ADDRESSED BY THE MANUFACTURER. *TR

DUE TO POOR MANUFACTURING AND LOW QUALITY PARTS, 1999-2004 JEEP GRAND CHEROKEES HAVE BEEN SUBJECT TO BREAKAGE OF INTERIOR PARTS CONTROLLING THE HEATING AND A/C SYSTEMS, INCLUDING BUT NOT LIMITED TO THE BLEND DOORS AND ACTUATOR. THIS SYSTEM BREAKDOWN CAN OCCUR SUDDENLY, AND CAN AFFECT BOTH THE A/C AND HEATING SYSTEMS. WHEN THIS OCCURRED TO MY 2002 JEEP GRAND CHEROKEE LTD. IT WAS IN THE DEAD OF WINTER (DEC 2009) AND THE WEATHER HAD BEEN EXTREMELY COLD. I WAS UNABLE TO PROPERLY DEFROST MY WINDOWS, CAUSING EXTREME DIFFICULTY IN SEEING OUT OF MY WINDSHIELD AND RIGHT SIDE MIRROR. BECAUSE OF THIS I WAS OFTEN HAVING TO ROLL DOWN MY WINDOWS--EVEN IF IT WAS SNOWING--IN ORDER TO DRIVE SAFELY TO SCHOOL AND WORK. IN MARCH I TOOK MY CAR TO A LOCAL JEEP DEALERSHIP TO GET MORE INFORMATION ON THIS ISSUE AND I WAS TOLD BY ONE OF THE SERVICE ADVISOR...

BLEND DOORS ON MY 2002 JEEP GRAND CHEROKEE NOT WORKING. *TR

I HAVE BEEN HAVING TROUBLES WITH THE BLENDER DOORS CLOSING ALL THE TIME ON MY 2002 JEEP GRAND CHEROKEE LIMITED. I HAVE HAD THE SUV FOR NOT EVEN 3 YEARS AND THE DOORS HAVE CLOSED 4 TIMES ALREADY. 2 MONTHS AGO THEY CLOSED AND IT COST $1,200 TO FIX IT, NOW 2 MONTHS LATER THE DOORS CLOSED AGAIN TODAY 5/27/10. THIS IS GETTING OUT OF HAND. THESE BLENDER DOORS HAVE A DEFECT AND CHRYSLER IS NOT DOING ANYTHING ABOUT IT. *TR

THE HEATER FAILED IN MY 2002 JEEP GRAND CHEROKEE. THIS IS APPARENTLY A VERY COMMON PROBLEM IN THIS MODEL. PREVIOUSLY THE SEAT HEATERS OVERHEATED AND THE POWER STEERING HOSE FAILED. *TR

HEATING SYSTEM IN 2002 JEEP GRAND CHEROKEE FAILED. I DON'T HAVE DEFROST, HEAT. HAVE HEARD OF NUMEROUS COMPLAINTS FROM OTHER CHEROKEE OWNERS WITH THE SAME PROBLEM. *TR

ANOTHER BLEND DOOR FAILURE COMPLAINT. PASSENGER SIDE WENT OUT AND NOT ONLY DOES IT AFFECT THE DEFROSTING ABILITY ON THAT SIDE OF THE WINDSHIELD, A PASSENGER HAS NO HEAT EITHER. BLOWS COLD AIR ALL THE TIME. CHRYSLER HAS KNOWN ABOUT THIS PROBLEM WITH THE CHEAP PLASTIC PARTS USED TO MANUFACTURE THE UNITS BUT DON'T TAKE RESPONSIBILITY FOR DOING THE RIGHT THING AND FIXING THEM FOR FREE. MY JEEP HAD LESS THAN 50K ON IT WHEN THE FAILURE OCCURRED. I WILL NEVER BUY ANOTHER CHRYSLER PRODUCT. THEY ARE DESPICABLE. *TR

JEEP GRAND CHEROKEE BLEND DOORS. THAT ALL I HAVE TO SAY. THE BLEND DOORS ARE JUNK. THEY BREAK IN EVERY JEEP GC. IT'S A 1500 DOLLAR JOB THAT CHRYSLER IS AWARE OF. IT HAPPENS IN ALL JEEPS. THE DOORS BREAK, LEAVING THE PASSENGER COMPARTMENT WITH NO HEAT. CHRYSLER IS AWARE OF THIS PROBLEM. THEY HAVE ISSUED A TECH BULLETIN, BUT STILL THEY DO NOT RECALL THIS PART. THIS IS '!@#$%. THEY KNOW ABOUT THE PROBLEM. FIX IT FOR THE CONSUMER ALREADY! *TR

I AM PAYING FOR A 2002 JEEP GRAND CHEROKEE THAT I PURCHASED USED IN 12-06. I HAVE HAD A PROBLEM WITH THE HEATER 6 MONTHS AFTER I PURCHASED IT USED, WHICH THE DEALER WOULD NOT REPAIR. I CALLED CHRYSLER AND NO ONE RETURNED MY CALL UNTIL THIS MONTH. I RECEIVED A RECALL ABOUT THE FAN BLADES AND TOOK IT INTO THE SHOP. PRIOR TO THE SHOP APPOINTMENT THE CHECK ENGINE LIGHT CAME ON, I ASKED THE SERVICE TECH TO CHECK WHY THE HEATER WAS NOT WORKING AND WHY THE CHECK ENGINE LIGHT WAS ON. HE CALLED ME TO TELL ME THAT THE RECALL PART WAS ON BACK ORDER AND THAT THE BLEND MOTOR AND DOORS ON THE HEATER WERE BROKEN AND THAT THE LEAK DETECTION PUMP HAD GONE OUT, WHICH WOULD PREVENT ME FROM GETTING IT INSPECTED. HE ALSO TOLD ME THAT THE HEATER PLUGS WERE MELTED AND IT NEEDED...

MY 2002 GRAND JEEP CHEROKEE'S HEAT STOPPED WORKING AND I WAS TOLD THAT THE ACTUATOR DOORS WERE GONE. THIS WAS DETERMINED BY THE DEALER. NOW MY HEATED SEATS HAVE STOPPED WORKING.THE DEALERSHIP GAVE ME AN ESTIMATE OF ABOUT 1300.00 DOLLARS TO REPLACE THE DOORS. *TR

NO HEAT ON PASSENGER SIDE IN JANUARY 2007, SEPTEMBER 2007 NO AIR BOTH SIDES, THEN NOVEMBER 2007 NO HEAT AT ALL FROM BOTH SIDES. THE JEEP HAS BEEN IN AND OUT OF THE DEALER ALL YEAR WITH MANY ISSUES, AS EMPLOYEE OF CHRYSLER , I LOVE MY JEEP THAT I PURCHASED NEW, JUST NOT HAPPY WITH THE REPAIR WORK NEEDED ALL THE TIME . *TR

THE HEATER/AIR CONDITIONER BEGAN WORKING LESS AND LESS EFFICIENTLY. NOW NEITHER WILL WORK AT ALL, CAUSING MY FAMILY TO TRAVEL UNLESS THE WEATHER IS JUST RIGHT. NOTHING THE REPAIRS COST $1400. *TR

THIS IS A COMPLAINT AGAINST NHTSA. IT APPEARS THAT EVEN THOUGH 100'S OF CONSUMERS HAVE COMPLAINED ABOUT A CERTAIN PROBLEM WITH THE AIR FLOW BLEND DOOR ON JEEP GC PRODUCTS NOTHING IS DONE ABOUT IT. IT IS OBVIOUS THAT THIS FAILURE IS A DEFECT AND NOT A WEAR AND TEAR PROBLEM. I AM SURE THERE WOULD BE 1000'S OF COMPLAINTS BUT NOT EVERYONE KNOWS ABOUT THIS SITE OR THEY DON'T HAVE A COMPUTER. IT APPEARS THAT THIS WEB SITE DOES NOTHING BUT ALLOW PEOPLE TO VENT ABOUT PROBLEMS WITH THEIR VEHICLES AND NOTHING MORE IS DONE ABOUT IT OR WITH IT. OUR TAX DOLLARS PAY THESE PEOPLE AT NHTSA AND WE GET NOTHING FOR OUR MONEY. THEY DON'T CARE ABOUT HOW MUCH MONEY IT COSTS YOU TO FIX SOMETHING AND THEY DON'T CARE IF IT COULD POSSIBLY CAUSE YOU PHYSICAL INJURY OR EMOTIONAL PAIN BECAUSE IF THEY DID THEN THEY...

BLEND DOORS FAILED ON 2002 JEEP GRAND CHEROKEE. CANNOT GET HEAT, DEFROST WINDOWS, ETC. THIS HAPPEN TO OUR JEEP AT 80,000 MILES, BUT I HAVE HEARD FROM MANY JEEP OWNERS WITH THE SAME PROBLEM, SOME HAPPENING AS SOON AS 40,000 MILES. THIS IS CLEARLY A MANUFACTURING DEFECT AND IS A SAFETY ISSUE IF ONE CANNOT PROPERLY DEFROST WINDOWS. COST IS $1,200 TO REPAIR PER DEALERSHIP. *TR

APPARENTLY THERE IS A HUGE NUMBER OF JEEP GRAND CHEROKEE OWNERS WITH DEFECTIVE BLEND DOOR ACTUATORS. I AM ONE OF THEM. I OWN A 2002 JEEP GRAND CHEROKEE LIMITED AND HAVE NO HEAT ON MY PASSENGER SIDE. NO DEFROST, BIG SAFETY ISSUE. DEALER QUOTES OVER $1,000 TO REPAIR. I CAN'T AFFORD THAT! *TR

IN THE FALL OF 2007, THE HEAT ON THE PASSENGER SIDE OF 2002 JEEP GRAND CHEROKEE STOPPED WORKING. I DID SOME ONLINE RESEARCH AND THIS PROBLEM WAS SO COMMON THAT I EASILY FOUND PLENTY OF PEOPLE WITH THE EXACT SAME PROBLEM THAT WERE ABLE TO SELF-DIAGNOSE THE PROBLEM USING THE JEEPS INTERNAL COMPUTER TO OUTPUT THE SYSTEM FAULTS. USING THE SAME METHOD TO ENTER THE AZC SELF-DIAGNOSTIC MODE, THE CLIMATE CONTROL DISPLAY OUTPUT THE SYSTEM FAULT CODES 52-54-56. SINCE MOST OF THE CONSUMERS I'VE RUN INTO WITH THIS PROBLEM GET THAT EXACT CODE, OR HAVE HAD THE SAME PROBLEM DIAGNOSED BY A JEEP DEALERSHIP SERVICE DEPARTMENT, I ALREADY KNOW THAT IT WILL COST ANYWHERE FROM $1000+ TO BE REPAIRED, THE MAJORITY OF IT BEING LABOR AS THE ENTIRE INSTRUMENT PANEL ASSEMBLY HAS TO BE REMOVED. TO ADDRESS THIS PROBLEM, DAIMLER-CHRYSLER RELEASED TSB 2400104 - NEW HVAC SUB-ASSEMBLY REPLACES BLEND OR...

THE A/C, AND HEATER DOES NOT WORK PROPERLY!!! ON MY 2002 JEEP GRAND CHEROKEE LIMITED (WJ), THE HEAT DOES NOT WORK ON THE DRIVERS SIDE, THERE IS A FLAP UNDER THE DASH THAT IS JAMMED SHUT, SO THE HEAT ONLY WORKS ON ONE SIDE!!! I GOT A QUOTE TO GET THIS PROBLEM REPAIRED, AND IT WAS 800-1200 MINIMUM!!!! *TR

THIS IS IN REGARDS TO THE BLEND DOOR ISSUE ON JEEP GRAND CHEROKEE MODELS THAT HAVE THE DUAL CLIMATE CONTROL. THE FACT THAT THIS ISSUE IS IMMINENT IN NEARLY EVERY ONE OF THESE VEHICLES IS DISTURBING ENOUGH IN ITSELF, BUT WHAT IS DOWNRIGHT UNACCEPTABLE IS THAT THE AVERAGE COST TO REPAIR RANGES FROM 1000.00-1300.00!! THIS ISSUE IS SO PREVALENT THAT 3 DIFFERENT JEEP SITE FORUMS HAVE HAD SO MANY JEEP OWNERS BRING THIS UP THAT IT HAS BECOME A POSTED ISSUE. I HAVE RECENTLY PURCHASED A 2002 MODEL AND, KNOCK ON WOOD, HAVE NOT EXPERIENCED THIS ISSUE. I BELIEVE IT ACTUALLY MAY HAVE ALREADY BEEN TAKEN CARE OF, BUT IN THE EVENT THAT I AM WRONG, I CAN ONLY HOPE AND PRAY THAT DC/JEEP HAS STEPPED UP AND DONE WHAT IS RIGHT, AND, AT THE VERY LEAST, AS A RECALL/TSB, COVERS A LARGE PORTION OF THIS REPAIR. *TR

THE CAR DOES NOT BLOW HEAT ON THE PASSENGER SIDE. APPARENTLY THERE IS A WELL KNOWN PROBLEM WITH THE BLEND DOORS AND THE ACTUATORS. IT IS VERY DANGEROUS IN THE WINTER WHEN THE RIGHT SIDE OF THE JEEP DOES NOT DEFROST BECAUSE NO WORM AIR BLOWS OUT. NO VISIBILITY. *TR

BROUGHT MY 02 JEEP GRAND CHEROKEE IN NOVEMBER 2007 HAD PROBLEMS WITH THE HEAT MODE BLOWING COLD OUT THE PASSENGER SIDE VENTS. TO STOP THIS AND MAKE THE PASSENGER SIDE FEEL THE HEAT I HAD TO TAPE UP THE VENTS ON THE PASSENGER SIDE. WELL SUMMER OF 2008 BEGAN SO I REMOVE THE TAPE FROM THE VENTS. WITH THE AC ON THE AIR FLOW WAS WEAK THE AS WAS RECHARGED THE DRIVER SIDE BLEW COLD, BUT PASSENGER SIDE WAS WEAK. AROUND AUGUST TURN ON THE AC NOTHING BUT A VERY WEAK AIRFLOW FROM BOTH SIDES. THE POSSIBLE VILLAINS BLEND AIR DOORS AND THE AIR RECIRCULATION DOOR. COST FROM DEALER TO REPAIR 1,000.00 TO 1,200.00 THE WINTER OF 2008/ 2009 IS APPROACHING NO HEAT AND *NO DEFROST. COULD GET DANGEROUS. PLEAS HELP!!!!!!!! *TR

THE HEAT ON THE PASSENGER SIDE OF THE JEEP IS BLOWING COLD AIR IN WINTER, EVEN WHEN IT IS SET TO MAXIMUM HEAT. THE DEALER TOLD ME THAT THERE IS A SERVICE BULLETIN ON THE BLEND DOOR AND THEY WANT OVER $700 DOLLARS TO FIX IT. MY QUESTION IS IF THEY KNOW THERE IS A PROBLEM WITH IT FROM DESIGN HOW COME THEY DON'T FIX IT FOR FREE AND WHY SHOULD I PAY FOR IT WHEN THEY KNEW THEY SOLD ME A BAD DESIGN. ALSO NOW THE AC IS BLOWING HOT AIR AND THEY ARE TELLING ME IT IS THE SAME PROBLEM WITH THE BLEND DOORS. THIS IS A SAFETY ISSUE SINCE IN THE WINTER I CAN NOT DEFROST THE FRONT WINDSHIELD AND HAVE TO PULL OVER TO CLEAN THE ICE AND FOG BUILD UP FROM INSIDE THE WINDOW. *TR

HVAC UNIT IN MY JEEP WJ, 2002, BROKE. DETERMINED TO BE BLEND DOOR AND RECIRCULATION DOOR MALFUNCTION. COMMON PROBLEM WITH VERY EXPENSIVE REPAIR!!! *TR

I OWN A 2002 JEEP GRAND CHEROKEE LIMITED AND IT IS EQUIPPED WITH DUAL CLIMATE CONTROL. I'VE NOTICED A FUNNY NOISE COMING FROM THE BOTTOM OF THE DASH IT ALMOST SOUNDS LIKE A TWISTING OR A CLAPPING NOISE. JUST RECENTLY I NEEDED TO TURN ON MY HEATER BECAUSE IT WAS REALLY COLD OUT AND FOR SOME REASON ALTHOUGH THE TEMP WAS SET ALL THE WAY TOO HIGH IT WAS STILL BLOWING COLD AIR FROM THE DRIVER SIDE. HOWEVER, THE PASSENGER SIDE STILL WORKED FINE. I BOUGHT THIS VEHICLE USED AND I KNOW IT WILL COST WAY MORE THAN I CAN EVER AFFORD FOR THIS REPAIR. I HAVE INVESTIGATED THIS ISSUE AND UNDERSTAND THAT THE PROBLEM IS IMMINENT TO JEEP OWNERS. I UNDERSTAND THAT THE COMPANY FEELS IT IS NOT A SAFETY ISSUE BUT A LUXURY. HOWEVER IT IS FOR MOST OF US THAT OWN A SUV IT IS BECAUSE WE...

COLD AIR BLOWING FROM PASSENGER SIDE VENTS AND WINDSHIELD DEFROSTER REGARDLESS OF CONTROL OR TEMP SETTINGS. DRIVER SIDE TEMP ADJUSTMENTS WORK PROPERLY, BUT PASSENGER SIDE AND WINDSHIELD DEFROSTER CONTROLS DO NOT PROVIDE ANY HEAT. WINDSHIELD DOES NOT DEFROST, AS TEMP MIX IS NOT FUNCTIONING FOR PASSENGER VENTS OR FOR WINDSHIELD DEFROSTER. PROBLEM HAS NOT BEEN RESOLVED. *TR

I PURCHASED MY 2002 JEEP GRAND CHEROKEE LIMITED 2 YEARS AGO, AND 6 MONTHS AGO, THE PASSENGER SIDE BLEND DOOR ACTUATOR DIED AS WELL AS BROKE THE BLEND DOOR ITSELF UPON INSPECTION. THIS IS A PROBLEM AS IT TAKES REMOVAL OF THE ENTIRE DASHBOARD, DRAINING AND REFILLING THE AC SYSTEM AND DRAINING AND REFILLING THE ANTIFREEZE. I SPENT GREATER THAN 10 HOURS WORKING ON THE PROBLEM. THIS IS NOT JUST AN ISOLATED INCIDENT AS THERE ARE ENTIRE WEBSITES SET UP TO HELP FIX THE PROBLEM (HTTP://WWW.WJJEEPS.COM/HVAC_SUB_ASSEMBLY.HTM). THERE ARE NUMEROUS MESSAGE BOARDS RELATING THIS PROBLEM, AND EVEN A COMPANY WHO SELLS A METAL REPLACEMENT TO THE PLASTIC PART. *TR

I OWN A 2002 JEEP GRAND CHEROKEE OVERLAND EDITION WITH DUAL CLIMATE ZONES. WHEN THE HEAT IS ON, PASSENGER SIDE VENTS BLOW COLD AIR. DRIVER SIDE VENTS BLOW WARM AIR. IN LOOKING ON JEEPFORUM.COM, IT APPEARS THAT THIS IS HAPPENING TO MOST PEOPLE WHO OWN THIS TYPE OF VEHICLE. IT IS A KNOWN BLEND DOOR ISSUE. *TR

CLIMATE CONTROL BLEND DOOR FAILURE - FOGGED UP FRONT WINDOW AND NEARLY CAUSED AN ACCIDENT. *TR

HEATER BLEND DOOR BROKEN. NO HEAT AT ALL!! KIND OF DANGEROUS IF YOU CAN'T DEFROST YOUR WINDOWS BECAUSE YOU HAVE NO HEAT. THIS IS A VERY COMMON OCCURRENCE FOR MY MODEL JEEP GRAND CHEROKEE. *TR

MY 2002 JEEP GRAND CHEROKEE FIRST LOST HEAT ON THE PASSENGER SIDE, THEN A FEW MONTHS LATER THE DRIVERS SIDE HEAT WOULD NOT WORK AS WELL. I WAS TOLD BY MY MECHANIC THAT THE BLEND DOORS ACTUATORS WERE NOT WORKING AND WOULD HAVE TO BE REPLACED AT THE COST OF $800-$1000. I HAVE BEEN TOLD THIS IS A VERY COMMON PROBLEM. I THINK THIS SHOULD BE A RECALL ISSUE. PLEASE ADVISE. *JB

THE HVAC BLEND DOORS ON MY 2002 JEEP GRAND CHEROKEE (WJ) OVERLAND FAILED AT APPROXIMATELY 88, 000 MILES CAUSING A LOSS OF HEAT AND DEFROST ABILITIES. DUE TO THE CONSTRUCTION OF THE VEHICLE IT WILL REQUIRE A TRAINED MECHANIC A QUOTED SEVEN HOURS OF LABOR TO REPLACE A PLASTIC PART WHICH HAS FAILED. I BELIEVE THIS IS A SAFETY HAZARD, THE LOSS OF DEFROST ABILITY, THAT JEEP MANUFACTURES HAVE BEEN AWARE OF AND THAT A RECALL SHOULD BE ISSUED SO THAT THESE JEEPS, REGARDLESS OF MILEAGE MAY BE REPAIRED AT NO COST TO THE CURRENT JEEP OWNER. *TR

EVENTS LEADING UP TO FAILURE: NORMAL USAGE OF VEHICLE CABIN COMFORT AND SAFETY CONTROLS (AIR CONDITIONING/DEMISTER) SYSTEMS. FAILURE: CABIN AIR CONDITIONING SYSTEM NOW DOES NOT REGULATE TEMPERATURE. THE SYSTEM CANNOT BE MADE TO USE HOT OR COLD AIR ON DEMAND. IN INVESTIGATING THIS FAILURE, IT HAS COME TO MY ATTENTION THAT 99% OF ALL OTHER OWNERS OF THIS VEHICLE REPORT EXPERIENCING A FAILURE OF THE 'TEMPERATURE BLEND CONTROL DOORS' WITHIN THE 'A/C BLEND ASSEMBLY'. CONSEQUENCES: THE VEHICLE DEMISTER IS UNABLE TO CLEAR THE FRONT WINDSHIELD OF MIST/FOGGING (EFFECTIVELY, DEPENDING ON OUTSIDE TEMPERATURE). CORRECTIONS: NO CORRECTIONS HAVE BEEN PERFORMED DUE TO COST PROHIBITIVE EXPENSE TO DO SO. THE LOCAL DEALERSHIPS QUOTE A PRICE OF AROUND $1800.00 TO REPAIR THE FAILURE, WHILE OBTAINING PARTS AND PERFORMING SELF-REPAIR WILL COST UPWARDS OF $300.00 PLUS TIME SPENT. *TR

2002 JEEP GRAND CHEROKEE BLOWING COLD AIR. I HAD THIS LOOKED BY THE DEALER AND THEY SAID THAT THEY NEEDED TO REPLACE HVAC SUB ASSEMBLIES. THEY QUOTED ME $1000 TO HAVE THIS FIXED.

2002 JEEP GRAND CHEROKEE LTD WITH DUAL ZONE CILMATE CONTROL SYSTEM. AT 50,000 MILES THE PASSENGER SIDE HEAT AND DEFROSTER STOPPED WORKING. NOW IN AT 60,000 MILES THE DRIVER SIDE HEATER HAS ALSO FAILED. PER A WEB SITE IT IS A VERY COMMON OCCURANCE WITH THIS VEHICAL. IT APPEARS CHYRSLER IS NOT TAKING ANY ACTION TO RECALL THIS SAFTEY ISSUE.

I OWN A 2002 JEEP GRAND CHEROKEE OVERLAND. E EVENTS LEADING UP TO THE FAILURE OF THE VENTILATION SYSTEM WERE (1) FOGGING OF FRONT WINDSHIELD,(2) FOGGING OF FRONT PASSENGER WINDOWS, (3) FAILURE OF PASSENGER'S HEAT WHILE STILL MAINTAINING THE DRIVER'S HEAT FUNCTION, AND (4) ONLY COLD AIR RELEASED ON PASSENGER'S SIDE . CONSEQUENTLY THE WINDSHIELD AND FRONT WINDOWS DID NOT CLEAR. WHATSOEVER CAME THE PASSENGER'S SIDE FLOOR AND DASHBOARD VENTILATION SYSTEM. TO CORRECT THIS PROBLEM, A BLEND AIR DOOR WAS NECESSARY FOR APPRATELY $1,200. ACCORDING TO THE CERTIFIED SERVICE DEPARTMENT AT THE LOCAL JEEP DEALER AND ONLINE FORUMS, THIS HAS BECOME A VERY COMMON PROBLEM FOR 2000-2004 JEEP GRAND CHEROKEES WITH DUEL ZONE VENTILATION SYSTEMS.*AK
