hi.....i have an 87 iroc with dual electric fans and i just wanted to know how to setup the wires with a switch so i can activate the fans so they can be running constantly through out my driving? i did see something about it on the message boards but i cant open it cause i need a certain reader for it. i did how ever see one time an old post of the fan setup but its not there anymore. so if there is a diagram or some article about it or old post. please let me know or send the information in my email address. thanks again for the help.:hail: :hail: :hail: :hail:

 

Do a search for "manual and fan and switch" and you'll find that diagram.

It's easy enough, you just use a wire splice to tap into the green/white wire on the fan relay. Run that wire to one post on a switch, run a wire from the other post on the switch to a good ground. That way, when you hit the switch it cuts the fan on by grounding the relay instead of having a live wire running to a toggle switch.


IF you have dual fans, I'm fairly certain, that if you tap into the green/white wire of the SECONDARY fan relay, when you cut the fan on, the primary will come on as well.

I just tried this and only the secondary fan came on.
I have 2 switches, one to each relay since neither of my fans would come on normally.
