AIR CONDITIONER BEGAN MAKING LOUD NOISE WITH ACCELARATION, THAN WITHIN A FEW MOMENTS BEGAN BLOWING HOT AIR. THE COMPRESSOR AND CLUTCH WERE REPLACED AND WITHIN 1 WEEK THE PROBLEM BEGAN AGAIN. I KNOW 7 PEOPLE WITH GM VEHICLES AND THEY ALL ARE HAVING THE SAME PROBLEM WITH THEIR AC'S. IT SEEMS TO ONLY BE A PROBLEM WHEN THERE IS HIGH HUMIDITY. HOWEVER WHEN I WENT TO RETURN THE FAULTY COMPRESSOR AND CLUTCH I HAD PURCHASED IT SEEMS THEY ARE ON NATION WIDE BACKORDER. IT SEEMS TO ME THERE IS A PROBLEM HERE.

VEHICLE SPEED CONTROL
THE TRUCK WAS PARKED AND RUNNING. IT SUDDENLY BEGAN TO IDLE AS IF SOMEONE WAS PUSHING DOWN ON THE GAS. I IMMEDIATELY SHUT THE CAR OFF. I TURNED IT BACK ON AND THE ENGINE LIGHT WAS ON AND IT READ "REDUCED ENGINE POWER". IT SEEMED TO DRIVE OK. I CALLED DEALERSHIP AND MADE APT FOR TUESDAY. (IT WAS THURSDAY) THE NEXT DAY I DROVE IT TO LOCAL GARAGE TO READ ENGINE CODE. IT WAS P2135. THE TRUCK THEN STOPPED ACCELERATING. IT WOULD NOT GO OVER 25MPH. IT TOOK ABOUT 2 FULL MIN TO GET IT AT THAT SPEED. WHEN I WOULD BREAK, THE TRUCK WOULD JUMP AS IF DID NOT WANT TO STOP. THE DEALERSHIP DIAGNOSED THE PROBLEM AS THE THROTTLE POSITION SENSOR COVER. I WAS INFORMED THAT GMC IS AWARE THAT THERE IS A PROBLEM AND HAS SINCE CORRECTED IT. HOWEVER, THERE IS NO RECALL AS THERE IS NO ALLEGED SAFETY ISSUES. I BELIEVE THAT WHEN YOU HAVE A 1,2, AND 3 YEAR OLD IN THE TRUCK IN RUSH HOUR, IT IS DARK OUTSIDE, AND YOU ARE AN HOUR AWAY FROM HOME IT IS A HUGE SAFETY ISSUE WHEN YOUR TRUCK WON'T ACCELERATE! I HAVE CONTACTED GMC WHO REFUSES TO TAKE RESPONSIBILITY FOR THIS ISSUE. PLEASE ISSUE A RECALL AS THIS IS A KNOWN PROBLEM. *TR
