1994 LEXUS LS400 Electrical Systemwiringinteriorunder Dash Problems

SINCE 80,000 MILES, THE DASHBOARD LIGHTS HAVE DISPLAYED INTERMITENT LIGHTING. THE PROBLEM IS WORST WHEN THE CAR IS COLD (BELOW 60F). WHEN YOU START IT UP, THE DASH IS DARK. THEN, AS THE CAR WARMS UP, THE NEEDLES WILL FLICKER AND COME ON ( IF YOU ARE LUCKY), FOLLOWED BY THE BACKGROUND FLICKERING AND THEN COMING ON. WHILE THIS HAS HAPPENED WHILE THE CAR WAS MOVING, GENERALLY IT IS WHEN THE VEHICLE IS COLD. NOW, WITH THE MILEAGE OVER 100,000 BLACKOUT IS NEARLY 100% OF THE TIME. LEXUS DOES NOT ADMIT THEY HAVE HEARD OF THIS ISSUE. THEY TELL YOU JUST REPLACE THE SPEEDOMETER FOR $1200-$1500. SORRY, I DON'T HAVE THAT KIND OF MONEY TO THROW AWAY. I FEEL THIS IS A SAFETY ISSUE AND A RECALL IS WARRANTED. ONE DOES NOT KNOW IF THEY ARE: OVER THE SPEED LIMIT, LOW ON FUEL, OVERHEATING OR THE BATTERY IS WEAK. FOR...

I HAVE A 1994 LEXUS LS400. WHEN THE TEMPERATURE IS BELOW 65F, THE ENTIRE DASHBOARD LIGHTS INCLUDING THE SPEEDOMETER, GAS GAUGE, AND ODOMETER GO DARK. AFTER 20-30 MINUTES OF DRIVING, THEY FINALLY COME ON. THIS IS A SERIOUS SAFETY HAZARD BECAUSE I AM NOT ABLE TO SEE THE SPEED AT WHICH I AM GOING. I UNDERSTAND THAT THIS IS A VERY COMMON PROBLEM WITH THE LS 400 FOR THIS YEAR AS WELL AS OTHERS. MY UNDERSTANDING THAT TO FIX THIS PROBLEM REQUIRES THE INSTRUMENT CLUSTER TO BE REPLACED BY LEXUS AT A COST OF $1000+. SOME OTHER OWNERS HAVE REPORTED THAT THIS CAN BE FIXED BY ELECTRONIC TECHNICIANS FOR ABOUT $500.*JB

I HAD A 1994 LS400. EVERY MORNING, UPON A COLD START FIRST TIME, MY INSTRUMENT CLUSTER DOES NOT LIGHT UP IMMEDIATELY. THE FOLLOWING INSTRUMENTS ARE COMPLETELY DARK:- TACHOMETER (NEEDLE IS MOVING) SPEEDOMETER (NEEDLE IS MOVING) OUTSIDE AIR TEMPERATURE (DEAD) FUEL LEVEL INDICATOR (DEAD) ODOMETER (DEAD IE NO MILEAGE INCREMENTING) D, 2, L GEAR POSITION NOT SHOWING (P, R, N IS OK) CRUISE, POWER EC INDICATORS NOT SHOWING USUALLY AFTER 15 MINUTES OF CONTINUOUS DRIVING, THE LIGHTS WILL FLICKER FOR A MINUTE AND THEN COME ON FOR THE REST OF THE DRIVE. THE PROCESS IS REPEATABLE EVERY DAY. THIS IS A MAJOR SAFETY CONCERN AS I HAVE NO IDEA AT WHAT SPEED I AM DRIVING AT OR THE AMOUNT OF GASOLINE THAT IS IN MY CAR. MY WIFE IS AFRAID TO DIRVE THE CAR WITH THIS PROBLEM AS SHE MAY BE STRANDED ANYTIME. *AK

I HAVE A '94 LEXUS LS400 THAT HAS INTERMITTENT DASH LIGHT PROBLEMS. FROM WHAT I'VE READ ON THE INTERNET, THIS IS A VERY COMMON PROBLEM. WHEN THE WEATHER IS COOL THERE ARE NO DASH LIGHTS MAKING IT IMPOSSIBLE TO READ THE SPEEDOMETER, GAS GAUGE, ETC. THE DEALER TOLD ME IT WOULD COST $2,400. TO HAVE THIS REPAIRED. I BELIEVE THIS IS A SAFETY ISSUE AND VERY COMMON TO SEVERAL YEARS AND MODELS OF LEXUS. THANKS FOR ANY HELP.*AK

ON COLD MORNINGS DASH CLUSTER WILL NOT LIGHT UP. AFTER A WHILE WHEN CAR WARMS UP LIGHTS WILL START TO FLICKER AND THEN WORK FOR REST OF DAY. WHEN CLUSTER DOES NOT LIGHT UP NOTHING IS VISIBLE ON DASHBOARD. APPARENTLY THIS IS COMMON ENOUGH THAT THERE ARE TWO ENGINEERS ON EBAY SELLING REPAIRS. LOOK ON EBAY UNDER LEXUS CLUSTER REPAIR.PARTIAL COPY OF AD IF YOU OWN A 1993 OR 1994 LEXUS LS400 YOU ARE PROBABLY HAVING TROUBLE WITH YOUR DASH LIGHTS OR SOON WILL HAVE. LEXUS IS AWARE OF THE PROBLEM BUT WON'T WARRANTY IT SINCE THESE CARS ARE NOW 10 YEARS OLD. THE LEXUS DEALER WILL CHARGE YOU FROM $1400 TO $2000 TO REPAIR YOUR INSTRUMENT CLUSTER LIGHTS. ACTUALLY, THEY REPLACE 2 CIRCUIT BOARDS LOCATED BEHIND THE INSTRUMENT CLUSTER. THEY THEN THROW YOUR OLD BOARDS AWAY, THEY DON'T REPAIR THEM. THE NEW BOARDS THAT YOU JUST PURCHASED FROM LEXUS...

1994 LEXUS LS400 WITH BAD INSTRUMENT PANEL. THE PANEL FAILS TO LIGHT UP BELOW 55-60 DEGREES. SAFETY HAZARD. *LA

1994 LS400 DASHLIGHT PROBLEM,WHEN THE VEHICLE IS COLD NONE OF THE DASHLIGHTS WORK...???? WHAT IS GOING ON? THIS OCCURS DAILY, AND IS GETTING WORSE. I HAVE CALLED LEXUS ON THIS PROBLEM (ALONG WITH THE PEELING PAINT) AND THEY REFUSE TO FIX THE PAINT (VEHICLE ALWAYS GARAGED) UNLESS I PAY THEM $8000.00, AND INFORMED ME THAT THE DASHLIGHT PROBLEM CAN BE FIXED FOR $3000.00. I THOUGHT I BOUGHT A LEXUS, NOT A CHEVROLET. VERY UNSATISFIED CUSTOMER.*AK

DASH BOARD LIGHTS DO NOT WORK. BEFORE THEY WOULD FLICKER AND COME ON, NOW NOTHING

INSTRUMENT PANEL WILL NOT LIGHT UP AT ALL. THE GUAGES WILL NOT ILLUMINATED, YOU CANNOT TELL HOW FAST YOU ARE GOING, HOW MUCH GAS YOU HAVE, OR IF THERE ARE HAVE BEEN ANY TYPE OF ENGINE FAILURES, BRAKE FAILURES, ETC. THIS CONTINUES FOR DAYS TO WEEKS AT A TIME. THIS IS WORSE AT NIGHT, YOUR COMPLETELY IN THE DARK, YOU CAN'T EVEN SEE WHAT GEAR YOUR IN - IT IS VERY DANGEROUS.

THE WHOLE DASH WILL NOT LIGHT UP WHEN THE WEATHER IS COLD, AND CAUSE DRIVER NOT TO SEE ANY OF THE WARNING LIGHTS, SPEED, OR FUEL LEVEL. THIS LEAVES THE CAR OCCUPANTS IN A VERY DANGEROUS SITUATION. DEALER WANTS AN ABSURB AMOUNT OF MONEY ($1200) TO FIX PROBLEM, WHICH I BELIEVE IS A FACTORY DESIGN FLAW AND NEEDS TO BE RECALLED.

I HAVE A 1994 LEXUS LS400 WITH DEFECTIVE INSTRUMENT PANEL LIGHTING AND IT IS A PROBLEM ON A VERY LARGE NUMBER OF LS400 AUTOMOBILES. THIS PROBLEM PRESENTS A SAFETY HAZARD WHEN DRIVING ESPECIALLY AT NIGHT. LEXUS DOES NOT WANT TO ADMIT TO THIS DESIGN FLAW OVIOUSLY.

WHEN STARTING VEHICLE AND ENGINE, AND THE ENGINE IS COLD, CONSUMER STATES THE HEADLIGHTS DO NOT OPERATE. AFTER VEHICLE ENGINE HAS WARMED CONSUMER STATES THE HEADLIGHTS START TO FLICKER. CAUSE IS UNKNOWN. PLEASE PROVIDE ANY FURTHER INFORMATION. PH

WHEN THE WEATHER WAS COLD DASH LIGHT WOULD NOT WORK PROPERLY. CONSUMER STATED AFTER VEHICLE WARMED UP, DAH LIGHT WOULD START TO FLICKER. TS THIS WOULD ALSO CAUSE THE DASH LIGHTS TO GO OUT COMPLETELY AND THE ODOMETER TO MALFUNCTION . METER ASSEMBLY CIRCUIT BOARD HAD TO BE REPLACED. *TT *JB. *AK

INSTRUMENT PANEL LIGHTS GO OUT. CAN'T SEE ANY GUAGES ON DASH. TOOK VEHICLE TO DEALER, AND DEALER INDICATED THERE WAS A PROBLEM. *AK
