Hi- Does anyone know the best way to do this? Someone once setr up the Aux. cooling fan to run all the time by running a ground wire to one of the prongs on the Aux. Fan Relay under the hood. The wire became disconnected and I need to figure out which prong/socket to connect it back to.

What I should look for when testing the 5 or 6 relay sockets with a DMM?

Thanks.

I put a over ride switch in mine so I could run it when ever and its really nice, and then its supposed to run aautomaticly to but for some reason it dosent. And its kicking on my check engine light on, and its not running automaticly. But i dont know whats wrong with that. I dont know if that answers you question.

Pin #'s 85 and 86 are the coil contacts on a Bosch type relay, which is what you have in your PDC.

The other day when I directed my girlfriend to ground the relay over the phone, 2 of the big 'maxi' 30A fuses blew.. I guess she picked the wrong one lol. Yesterday I drove to the AutoZone parking lot, and tried again...I got it right.

Its the terminal closest to the front left of the vehicle. #85 I believe. I just stuffed a ground wire in that socket, replaced the relay ontop of it, and now my Aux. fan runs all the time! (the reason it wasnt working in the first place was because my a/c system is empty... Thanks
