My 05 is running fine till I turned on air conditioner. I hear a whinning sound when it idols. when I accelerate it feels like someone is pushing back on the front of my car and when i rev the engine or hot the gas to go the whinning sound gets louder. It also idols low when Im slowing down from hitting the gas.

Please email with your answers guy. The dealer ship cant look at for like 3 to 4 days. I hate the dealership. Please remebr car is perfect when the air is on. No hesitation normal idle just perfect.

your complaint is the whinning sound from the compressor?

 

LGNDLIME05GT,

How much whine are you hearing? Can you hear it with the windows up and the stereo on at a moderate level (i.e. a talk show playing so that you can hear itwith your caridling)? What kind of RPM numbers are you seeing it drop too when you let off of the gas? Does this RPM drop correct itself, or does it cause the engine to stall and/or sputter? What does your car idle at (approximately) when warm with the AC off? Keep in mind that there is a noticable difference in performance with the AC compressor engaged due to the parasitic drag on the engine, so what we are trying to determine is if this is normal, or if there is something seriously wrong with your car .

Is your AC blowing out cold air? Maybe you have a coolant leak and the whine is coming from the pump cavitating?

 

It could be a bad tensionerpulley...A/C would put more strain on it and make it more noticeable! could also be bad bearings in the compressor.
