95 740i aux fan problem
hello i have a 95 740i and have never seen the aux fan in the front of the radiator run. the car doesnt over heat but i notice on hot days the ac isnt the greatest. which i believe is because the ac head pressure gets too high i dont know where the relay is can someone walk me through where the relay is. thank you

Might not be a relay. take a look at the fusebox in the engine compt. There is a 50 amp fuse buried deep in the covered box that powers the fan! Take a look at it, it might be the source of your trouble.

thank you that was it now the fan came on several times and hasnt come on in a while yet the fuse is good. how does that fan function. does it only come on when needed or does it have a sensor that may be bad? if so do you know where that sensor may be or how do i check it?
