Aux Fan schematc

[dburt86]

Im looking for a pre 99 aux fan schematic

Mine doesnt turn on with the AC, but has power at 1 wire (cant recall which one) Not really a problem in a Connecticut November.

But i want to make sure the car has some over heat protection, just in case.

I can get the fan to run by appling 12v's to a different wire (lol cant remeber which one)

Im pretty sure its going to be just the resistors, but im cheap, and dont like spending money if i dont have to.

Go here:

Type aux in the search box, lower left and hit Search. You will need to hit 'Next' a few times to get to the fan. Click the + to drop the tree for schematic. Be sure to also read the bottom option 'Air conditioning'.

Thanks Qsilver7!!!! I found the 95 on wedophones.com but I saw it was only 2 speed. Time to diagnose this puppy.

stage 3 is reserved only for overheating?
will stages 1 or 2 come on to cool the engine if the AC is NOT on?
