A/C on toggles electric fans?

Postby SolidSTI » Thu Jan 31, 2013 8:12 am

There are a lot of threads and wiring diagrams of using two relays and a thermos-witch to activate electric fans. I have not seen anyone wire them to turn on when the A/C is running. It is very hot and humid here, so I kept the A/C in my AE. Just wanted to see if anyone had done this before I got hooking a multimeter all over the place trying to figure out a good way to do this.

Thanks guys

I havent done this but i have thought of a way to do this. i would look up the wiring from the aw11 and see if you can get it to work using the aw11 relays and control box.

That is a pretty good idea. Guess I'll have to start checking surrounding salvage yards.

I ran my fan off my ac on for a while and had two problems: engine didn't get up to temp very often and the ign fuse would blow pretty regularly. Some will put a larger fuse on their ign but that's a bad idea for obvious reasons.

I think I found my solution;

You can run the + from the A/C to this and you are in business.
