Owner report 10080999 · 2004-07-13 (July 13, 2004)

WHEN THE AIR CONDITIONER COMPRESSOR IS RUNNING THERE IS A NOTICEABLE LOSS OF POWER. WHEN ACCELERATING FROM A STOP IT IS NECESSARY TO INCREASE THE PRESSURE ON THE GAS PEDAL TO COMPENSATE FOR THE LOSS OF POWER IF THE COMPRESSOR CYCLES ON. IF THE COMPRESSOR CYCLES OFF DURING ACCELERATION YOU NEED TO LET UP ON THE GAS PEDAL TO COMPENSATE FOR THE INCREASE OF POWER. THE DEALER CLAIMS THIS I NORMAL FOR THIS VEHICLE. I KNOW OTHER PEOPLE THAT HAVE 1999 AND 2000 TRAIL BLAZERS AND HAVE NEVER HAD THIS TROUBLE. THIS VEHICLE IS NOT SAFE TO DRIVE. *LA
