Q: When I turn my AC, my car shuts down.

asked by on

My AC works, it cools down the car, the problem is that: I notice when car is in "P" (But it does it in every shift) shift, with my AC on, I flood my car and it accelerate good but when I release the pedal the motor sounds like it will shut down with no power (when I have the AC off it doesn't happen) The AC compressor is a Universal one, and has a single relay outside the relay box, its holded near the fan, and a cable goes from the battery to the relay than to the button, than to the compressor, It wasn't me who made that, I bought the car like that. So today I was in a downhill and I turn the AC on and inmedietly the car shut down, it has happen to me like 5 times, only when the AC is on. I also noticed that tha car vibrate a lot more when the AC is on. The point is that when I turn the AC the car either shut down or the motor loses like "power" to the point that look like its going to shut down. The AC doesn't have any rare sound, it just make the car vibrate a lot. ERICK
