I came home from work today and my engine was severely overheated.

My electric fan sensor or relay went bad. I have everything to do a quick fix. relay, wire, fuseable links, but no switch. I need to find a ACC connection under the hood that I can tap into to run the relay until I can fix it properly. Its getting dark and I need to drive to work tomorrow

Thanks for the help in advance!

 

Your looking to just hard wire the fan on a switch?

 

I just fixed it! I was looking for a ACC connection under the hood to turn the relay on once the ign was on, I didn't have enough wire to get through the firewall. But I scrounged and found a couple more feet and for now am running it off the Lighter

 

Glad to hear. So its just your relay thats bad?

 

I don't know. I haven't had a chance to check. I just need to get it working again so I don't fry it

I had no warning light either. I don't know if perhaps the light bulb is dead, or if there is something more wrong.

 

Try switching it with another relay you know is the same one. Keep us posted and just ask if you need anything else.

 

is there a way I can tell if the sensor or the relay is working correctly without having the engine up to temp?

 

The fan should kick on when the a/c gets turned on. Does your a/c work? I belive when the compressor kicks on it turns the fan on.

 

the AC doesn't work, Before I gutted it for the on board AIR it was dead from the factory switch. The compressor works but no power to it.
