2004 Chevrolet Silverado 1500

INTERMITTENT, YET HAPPENING ALLOT MORE LATELY. THE DRIVER SIDE AIR CONDITIONER KEEPS GOING TO HOT HOT AIR, AS IF IN FULL HEAT. MUST PULL OVER TO SIDE OF ROAD AND RESTART TRUCK TO GET AIR CONDITIONER WORKING AGAIN. IN SOUTH TEXAS, HEAT IS UNBEARABLE AS YOU MAY KNOW. ALREADY HAD INSTRUMENT PANEL OUT OF WARRANTY THAT I PAID FOR AND AFTER COMPLAINING TO CHEVY WAS REIMBURSED BECAUSE OF RECALL AND AM FINDING OUT THIS IS A VERY COMMON PROBLEM AS WELL WITH THE A/C GOING OUT. DON'T HAVE MONEY TO TAKE TO SHOP AND REPAIR AND AM LOOKING FOR ANSWERS FROM GM. *TR

SPEEDOMETER DOES NOT WORK CORRECTLY. THE SPEEDOMETER FLOATS AS YOU ARE DRIVING AND ALSO SHOWS MPH WHEN AT A COMPLETE STOP. SOMETIMES THE SPEEDOMETER STICKS AT 120 MPH. THIS IS HAPPENING EVERY TIME THE VEHICLE IS DRIVEN. THIS IS A MAJOR SAFETY ISSUE SINCE THE DRIVER DOES NOT KNOW HOW THE CORRECT SPEED THAT IS BEING DRIVEN. *TR

SPEEDOMETER AND GAS GAUGE DEFECTIVE. SPEEDOMETER WILL NOT WORK AT ALL. GAS GAUGE WILL NOT SHOW PROPER FUEL LEVEL. ALOT OF 2005 GM OWNERS ARE HAVING THIS PROBLEM, THIS SHOULD BE A RECALL. SPEEDOMETER, CAN'T TELL HOW FAST WE ARE GOING. IF THE GAS GAUGE IS NOT WORKING COULD CAUSE AN ACCIDENT IF THE VEHICLE STALLS ON THE HIGHWAY, ESPECIALLY IF YOU ARE OVER A HILL OR CURVE. VERY DANGEROUS. THERE ARE SO MANY PEOPLE COMPLAINING ABOUT THIS WHY ISN'T IT A RECALL? PLEASE HELP TO GET THIS RECALLED NO MATTER THE MILEAGE, WE NEED TO BE SAFE WHILE OPERATING OUR VEHICLE. I HOPE IT DOES NOT HAVE TO TAKE A LAWSUIT TO MAKE THIS A RECALL ITEM. *TR

INITALLY, THE SPEEDOMETER GRADUALLY STARTED DISPLAYING INCORRECT SPEEDS WITHOUT ALERTING ME TO A FAILURE IN THE SYSTEM. THERE WERE NO SIGNIFICANT ENOUGH CHANGES IN BEHAVIOR AT AROUND 95,000 - 100,000 MILES ON THE ODOMETER TO CAUSE ME TO NOTICE THE PROBLEM. IT WASN'T UNTIL ONE DAY WHILE I WAS GOING MUCH FASTER THAN THE SLOWER LANE TRAFFIC ON THE HIGHWAY THAT I NOTICED A SERIOUS DEVIATION IN THE READING ( I FINALLY FIGURED IT OUT WHILE STARTING TO DRIVE MUCH FASTER THAN REGULAR TRAFFIC FLOW WHILE THE SPEEDOMETER KEPT GRADUALLY DROPPING ANY TIME I SLOWED EVEN SLIGHTLY UNTIL IT REGISTERED AROUND 40 MPH WHEN I WAS PASSING MIDDLE-LANE TRAFIIC IN A 65 MPH ZONE). I STICK PRETTY CLOSE TO THE SPEED LIMITS AND OBSERVE RECOMMENDED SPEEDS (E.G. YELLOW SIGNS ON CURVED HIGHWAY) ESPECIALLY WHILE TOWING TRAILERS. HAD THIS HAPPENED TO SOMEONE ELSE WHILE PULLING A TRAILER AROUND THE MOUNTAINS OF COLORADO AND WYOMING, THERE COULD'VE BEEN A SERIOUS INJURY/DEATH LEVEL ACCIDENT. I DIDN'T SEE A RECALL ON THE INSTRUMENT CLUSTER OR SPEEDOMETER USING THIS SITES DATABASE SEARCH. *TR

STEERING COLUMN IS FAULTY IN TWO OF MY 2004 CHEVROLET SILVERADOS. HAD IT REPAIRED BY GM BUT IT KEEPS MESSING UP AND CAUSING VIBRATIONS, CLUNKING AND ALTERING THE STEERING . ALSO BOTH OF MY TRUCKS THE SPEEDOMETER HAS COMPLETELY QUIT WORKING AT 40,000 MILES. HOW SAFE IS THIS????? PLEASE PLEASE DO A RECALL ON THESE TWO ITEMS. *TR

TL*THE CONTACT OWNS A 2004 CHEVROLET SILVERADO 1500. WHILE DRIVING AT ANY SPEED, THE SPEEDOMETER WOULD ALWAYS INDICATE THAT THE SPEED WAS 55 MPH FASTER THAN WHAT THE VEHICLE WAS ACTUALLY TRAVELING. THE VEHICLE HAS NOT BEEN DIAGNOSED BY THE DEALER. THE CURRENT AND FAILURE MILEAGES WERE 83,000. UPDATED 08/04/09 *BF UPDATED 05/08/09.*JB

'04 CHEVROLET K1500 - THROTTLE BODY SENSOR THE ISSUE IS THAT THE TRUCK KEEPS COMING IN AND OUT OF "REDUCED POWER MODE" WHICH WHEN IT IS IN THIS MODE IT IS VERY HARD TO MAINTAIN SPEED WHICH IN TURN IS INHERENTLY DANGEROUS. IN '07 I HAD THE CONNECTIONS CLEANED AND REPAIRED (UNDER WARRANTY), ON JULY 7TH OF '08 I HAD THE WHOLE THROTTLE BODY SENSOR REPLACED (OUT OF WARRANTY), AND IT STARTED ACTING UP AGAIN ON JUNE 25TH OF THIS YEAR. I QUALIFIED FOR THE 12 MONTH REPAIR WARRANTY, BUT HAD DRIVEN OVER 12,000 MILES. OUT OF THE BLUE MY TRUCK GOES INTO REDUCED POWER MODE. I PULL OVER AND BASICALLY RESTART THE TRUCK A FEW TIMES AND APPARENTLY THE COMPUTER RESETS AND EXITS THE MODE. THIS WORKED FOR THE FIRST WEEK BUT NOW IT HAS TO SIT OVERNIGHT. THE CHECK ENGINE LIGHT WILL STAY ON FOR A DAY OR SO, BUT THEN WILL CLEAR. I HAVE TAKEN IT TO THREE DEALERSHIPS FOR DIAGNOSTICS AND NO ONE CAN PUT THEIR FINGER ON THE SPECIFIC PROBLEM. THE MOST CURRENT ONE HAS TOLD ME HE COULD REPLACE THE THROTTLE BODY SENSOR, BUT CAN'T GUARANTEE THAT WILL FIX IT. HE HAS THREE MORE '04 CHEVYS COMING IN AND OUT OF THE SHOP WITH THE SAME PROBLEM. WHAT THEY HAVE BEEN ABLE TO TELL ME IS SHOWN BELOW, BUT STILL HAVEN'T BEEN ABLE TO FIX IT. "SCAN REVEALED 2 P2135- THROTTLE POSITION SENSORS 1-2 CORRELATION. " USING YOUR SITE I HAVE FOUND THE FOLLOWING SERVICE BULLETIN: 060604026 (NHTSA ITEM NUMBER : 10020835). I DON'T MIND SPENDING THE MONEY FOR THE REPAIR, I JUST NEED TO KNOW WHAT I NEED FIXED. I'M WORRIED ABOUT PULLING ONTO THE HIGHWAY AND THEN LOOSING POWER AND CAUSING A WRECK. *TR
