I had the same problem with my 2000 TC, Check the blower control module. It's mounted on the fire wall in the engine compartment (right side) almost behind the throttle body. It should have a red and white label on it. It's kind of hard to get to, but that's probally your problem.
I had the same problem on my 99TC.
Tap on the control modual with a screwdriver.
My first guess would be the blower motor resister. My second guess would be the switch and or plug into the back of the switch.
A loose connection at the motor and/or bad ground at the blower motor. If it is getting current then the motor may have a bad spot/ high amp draw and need to be replaced.
Blown fuse? Bad blower motor? Bad blower motor resistor? Bad blower motor switch?
Could be, a blown fuse, a bad blower motor, a burned out blower motor speed resistor, a bad blower motor switch,
it sounds like your ignition switch, i ran into a similar problem, your power goes through your ignition switch for your blower motor.
Defective blower motor or blower motor resistor pack.
No, that would have no bearing on the blower motor. Check the fuse, blower motor resistro pack, and the blower motor itself.
I assume that you can see the blower motor from the engine compartment It would be near the firewall ( the metal wall that divides the passenger compartment from the engine compartment ) on the right side ( towards the passenger side ) of the engine
If you are referring to the blower motor squealing, then I would suspect the blower motor bearings have failed.
blower motor bad or no power to it chech fuses blower switch blower motor
I would suspect the blower motor speed resistor is bad.
I would suspect the blower motor speed resister is shot.
