When the air conditioner compressor is running there is a noticeable loss of power. When accellerating 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 has been made aware of the problem and have tried to repair the problem but now claim this is normal for this vehicle. I have owned two other Blazer and they did not have this problem. I also have driven another 1999 Blazer and it did not display this problem. This vehicle is not safe to drive. I has been necessary to turn off the A/C in traffic. Any help you may be able to give me on this matter would be greatly appreciated. I plan to file for arbitration with the BBB as per the manufactures warranty.
