My harness crapped out. It has been burning up relays since I got it, they would normally last about 6 months. Now the fan won't cycle with AC, so I replaced the relays and nothing. I took all 3 relays out and put one old one back in and it worked. Then turned the truck off, restarted it, and it won't work again. Took the relay out, put it back in, and it worked again. Then turned off the truck, and the fan kept running??? I had to pull the relay.


Can someone post a diagram so I can wire a relay in to be switched on with switched power. I don't care if the single fan runs constantly or not, at least it will run. I can use one of the relays that is still working and steal wiring from the harness. The truck doesn't overheat, but the AC wont' work when this is happening.

This is for an '04 with '05 efans and Nelson Harness.
Thanks guys,
S.C.

PS - I am going to bed now, so I can't answer any questions until the morning.
