Hello I have a 2005 gt. The cooling fan will not stay on when a/c is running. It will run for maybe about a min then turns off for a min and turn back on. I notice when at high speeds the a/c will bow ice cold but when stopped it will not blow as cold. But when again at high speeds its blows cold. When it is at idle the cooling fan will just cycle on and off. any help would be great.

 

Have you checked your fuses and relays?

I have checked the mini relay for high and low even switched them around as there the same also the pcm #2 is the same to I switched them around. If one of the other 2 pcm fuses where bad would the fan run at all? It runs fine when the car is at high speed just not idle.
