Fan Speed Controller

Hi, I have a 2000 Cavalier and the Fan Speed Controller used to work properly (at all four levels)....however, recently when i turn the fan speed controller to Level 1 or Level 2 (where Level 1 = Min, Level 4 = Max), nothing comes out...for all type of settings I tried (incl. AC). However, when i turn it to Level 3 or Level 4, it's cranked up to the MAX!!!

What is wrong with it? Is there a loose connection somewhere behind the instrument panel? If so, how can i fix it?

Thanks!

Sounds like a resistor burned out. They're usually mounted in the airstream at the motor. If you pull it out, it'll have a few spring-looking things on it. Those things corrode and burn out overtime. They do get hot.

The 2000 may not have the visable coils as the resistors are now part of the PC board but I agree it sounds like the resister pack.

Probably about $30 and failrly easy to replace.
