I have a 97 Honda civic DX. The car has 135k miles on it. When i put the AC/Heat on i lose power until i hit 2nd gear. The check engine light is not on and I have had the transmission and engine checked and there are no problems with either. I have done some research and everything i read say it could be the main relay or a short somewhere that is interfering with the fuel pump. But before i start ripping things out i would like to know if anyone has had this problem before and how they fixed it. As everyone knows trying to track down a short in the harness can be insanely time consuming. Any information anyone could provide would be greatly appreciated.

 

A better thread title will help others help you faster. When you turn the ac on does the car die if sitting at idle?

 

Listen to this guy^

Oh Ok sorry my mistake i will try to fix it. But to answer your question no it idles fine. which kinda makes me think that there is a short going to the fuel pump.
