On my 94 the fan isnt coming on.I start the car and take a test light to the middle wire and there is power but not to the bottom wire.The top wire is black which I believe is the ground.Now the bottom wire is thicker so I believe that is the power wire for the high apeed fan.The middle wire is smaller so is that the wire for the low speed fan.Now i turn the AC on and neither the front fan or the main fan come on.I think the front pusher fan is for the AC.I put in a new temp sensor on the passenger side of the intake manifold which i think tells the comp to turn on the fan.The little temp sensor on the thermostate housing I think is for the guage.Now all this testing is done with the temps up around the M on NORM.So if Im correct on everything what the heck could be the problem??? Now this car was just tunned and everything was fine until yesterday.Please help!
