About a week ago I turn on my A/C and my car started to vibrate to hard.... anyone know what this can be?

 

normal, depends on how "hard" it vibrated and you sure it was the car vibrating "hard"?

 

I mean to much... more than normal..

 

take it to the dealer.

 

our cars vibrate like crazy when the a/c is on i hate it, and there is a lag in power you can feel.

 

05 tc with 50,000 miles, my ac doesn't vibrate at all. In fact i can only tell it's on because I loose a slight bit of power. I'd have it checked.

Check the belt and compressor. If you can have a friend turn it on or off while you watch both. Its definitely not normal.

Vibration is normal. When your car stalls at a stop light then you have a problem. The only vehicles I've been in that don't vibrate with the A/C on were pickup trucks, both diesel and gas. And those things vibrate already as it is, A/C or not.

 

it might not be "normal" vibration. Could be the a/c compressor going bad. If it's making noises, take it into the dealer. If it's under warranty, take it in.

 

Check if your radiator fans work. They should both click on when you turn on the A/C. If a fan bearing breaks the stuck fan will cause a large load on the electrical causing ur car to vibrate at idle since the alternator is harder to turn.

 

I think that's the problem, because when I turn on the a/c the radiator fans click on then start the vibration. I dont know what can be because I have 2 gel batterys in my car to not make the alternator to overwork..
