HEATER BLOWER

Bill, without knowing anything about your setup. I would think that the temperature switch is a bimetallic strip that acts as a on/off switch much like for your furnace at home. Therefore, you should be able to bypass it BUT make sure you connect ground to ground on the motor etc. Use an ohmeter to find which wire of motor goes to ground. BTW have you heard any kind of noises at all from motor? Could simply be seized. I got mine going by spinning it with my fingers with power applied (ouch!!) but it did work then I simply sprayed WD40 liberally.

I'm not familiar with that model either, but I seriously doubt that the temperature switch is a simple bimetalic switch. Even in the decade earlier cars it was far more complicated than that. I'd be very careful as to where and to what I applied 12V. If you can disconnect the power cable from the blower itself and apply power to the blower there, that is probably the safest.

I know all about this car... When fan not blowing, I need you to do a few test... Turn your fan speed to high.

1. Turn your ignition key back a further bit more without stopping the engine, does it comes on? If yes, your ignition switch is bad.

1. If above not work, then with fan speed high... I want you to slap your passenger seat lower dash hard... if fan comes on, then your fan motor brushes is worn out.... need rebuild kit or motor.

2. If both above not working, then I want you to take the blower fuse out and replace it with a new one.

I guess a new blower is needed. I've tried everything, but the blower doesn't come on :o(
