I replaced the blower resistor, it was bad, still the blower did not work. I checked the wires on the harness to the resistor and no resistance between the wires coming from the selector switch. I don't know how to get to the switch without breaking something. I have checked all fuses related to the ac circuits.

Hello,

The blower motor goes out int hses cars and takes out the resistor. I would test the power at the blower motor and then if bad replace the blower. Here is a guide that will help you get the job done.

Check out the diagrams (Below)

Please let us know what you find. We are interested to see what it is.

Cheers, Ken

Maybe a problem with blower resistor? That should be close to blower motor, under dash, passenger side. You may be able to get at it through glove box, if not then have to get at it from under dash. Also, check blower fuse, left side of dash, check the fuse and voltage, goes hot with the key on.

Yesterday my blower fan worked only on 4 and 5. This is when I run either the ac or heat. Today it
only is working on the 5 (high) setting. The lower
settings are not working. Is something clogged?

I have a 2000 Impala with 103,000 miles and I am experiancing my 1st problem with it. The blower for the air and defrost has stopped working and I cannot seem to locate it. Is there a way to access it so as to fix it myself?

When I turn my heater on the fan no longer works. It used to not work on settings 1 & 2 and now none of the settings work (1-5) What could be the problem. I would prefer to fix it myself. If you could send a schematic or a picture that would help alot.
