Question Asked: what causes loud knocking when the ac is running?
September 14, 2012, 03:10 PM
when i turn the ac on high, the car knocks really loud, but if you turn the ac off the knocking goes away, but then returns within seconds but it's not as loud. this is driving me nuts, sounds like something is loose, and it's not the motor because i just put a new motor in the car 2 months ago.
