2004 CHEVROLET TRAILBLAZER 360 Electrical System Problems

NONE OF THE GAUGES IN THE INSTRUMENT CLUSTER WORK AT ALL. I HAD ALL OF THE STEPPER MOTORS, AND THE NEEDLES REPLACED. PARTS AND LABOR TOTALING $350.00, AND AS SOON AS I WAS DOWN THE STREET 4 OUT OF THE 6 DID NOT WORK,AND THESE REPAIRS WHERE JUST DONE IN 2015. NOW THE TWO THAT WERE WORKING JUST QUIT 3 DAYS AGO. I DO NOT KNOW HOW MUCH GAS I HAVE,I DO NOT KNOW HOW FAST I AM GOING, I DO NOT KNOW IF MY VEHICLE IS RUNNING HOT, OR IF THE BATTERY IS CHARGING. I HAVE NOTHING.

IN 2010 MY TRAILBLAZER WOULD NOT IDLE OR ACCELERATE PROPERLY, THE MECHANIC FOUND THE PRIMARY SMOG AIR PUMP NOT WORKING. COST TO ME $720.00. NEXT THE INSTRUMENT CLUSTER GAUGES STARTED JUMPING AROUND AND NOW THE SPEEDOMETER DOES NOT WORK AT ALL. ESTIMATED COST TO ME $480.00, I CAN'T AFFORD TO FIX IT.. THIRDLY THE WINDSHIELD WIPERS GO ON AND OFF WITHOUT WARNING. I WENT TO A DEALERSHIP AND A PRIVATE MECHANIC AND NEITHER COULD FIND THE WIPER PROBLEM. COST TO ME $68.00 FOR DIAGNOSTIC TIME AND LOTS OF DANGER AHEAD. SIMILAR GM VEHICLES/ SUV'S HAVE BEEN RECALLED FOR THE SAME REASONS, AND THESE VEHICLES ALL SHARE SIMILAR PARTS. MY DAUGHTERS ENVOY WAS RECALLED BECAUSE OF THE INSTRUMENT CLUSTER, REPLACED AT NO COST TO HER. SAME INSTRUMENT CLUSTER AS MY TRAILBLAZER. I CANDIDLY SPOKE WITH THE OWNER OF A CHEVY DEALER SHIP WHO SAID; "THESE PROBLEMS ARE COSTING THE OWNERS THOUSANDS...
