Aux. fans won't come on...
For the last few months I've been relying on the aux. fans to keep the engine cool while I stomach spending $600 on a new fan clutch. On Friday I noticed the temp going higher than before. When I got home and parked, I realized the fans didn't kick in. Fuses are ok....where else should I look?
Thanks, Craig

Pull out the wiring diagram....
Start with checking the temp switch and make sure the fan still works. $600 for a fan clutch? You can buy the toyota silicone fluid and refill that puppy -many claim reasonable sucess and it's cheap. Michael

I bought the CD's from someone years ago, but they're not original and I can't get them to work.
Not even sure where the temp sensor is, or how to make the fan's kick in. I found a MB junk yard a few miles from me and they have used fan clutches for $250. I don't want to take the time to try and make the old clutch work. Easer to buy a used one of bite it and buy a new one. Craig

You can also check the aux fans relay behind the fuse box, relays B and C I believe.

Under the red circle, there is a plug that you can pull, that makes the fans come on @ high speed. Pull carefully, as sometimes the plastic is brittle.
(rectangular plug w/ 2 round holes). Good Luck

Ok, pulled the plug and nothing happened. Does the engine have to be warm, because mine wasn't.
Thx,Craig
