Duel Fans 89 Iroc

One of my fans is out and i was wondering if there was a good webpage that i could order a new one?
Also i was wondering if there was a easy way to rewire the fans to a toggle switch inside so that i could turn them both on when ever i want?

thanks,
Garrett

I can't say is there are new ones still available but, you can try
www.car-part.com www.parts.com www.gmpartsdirect.com or click one of the advertising banners at the top of any forum page (including this one) for a used one.

As for as your fans go, using the 'search' function of this site will net you many results towards more commonly asked questions such as wiring a toggle switch to turn on your fans.
Here is a list using 'toggle switch fans'... you should find a satisfactory answer among one of these....

Thanks for all the facts it helped alot! Now im just scared that if i do make a toggle switch that i will mess something up or cut the wrong wire
I have another question since there is two fans, when the car heats up do both fans turn on at the same time or does one fan turn on a certain temp and the other turn on at a hotter temp?

sorry if i made that confusing

Not a problem and welcome aboard too, btw. There's nothing to sweat, you're only dealing with the ground to the relay.
The fans do come on at different temps. The primary is 220ºish and the secondary comes on at 238º. They also both run with the A/C depending on the year.

do you think that because my A/C is broken thats why one of my fans doesnt work? because i have never seen this fan turn on plus my machanic told me that the motor was busted but i never can trust him!! haha

If your A/C isn't working then neither of the fans will do anything if I recall correctly. Year depending, at least one fan should work with the A/C but, that's only if there is line pressure in the A/C system. The A/C pressure switch will unground and send a 'A/C pressure request' to the ECM telling the ECM that the A/C is running and thus, the ECM will turn on at least the primary fan. If there is no A/C line pressure, then the switch will stay grounded (pressure makes it open) and the (or neither) fan will run with A/C.
