2002 Trailblazer A/C Problem

[thebrug]

I have a 2002 Trailblazer LS with manual HVAC controls. I only have speeds 3,4 and 5. Nothing works on 1 or 2. I've been told that it is probable the blower motor resistor. Can someone help?

Could be. Usually when its the resistor it will only work on high. Could be the blower motor switch.

Had the same thing, resistor/relay on blower case behind glove box, 26.00.

Thanks for responding. Can someone give me an idea what this resistor looks like. I looked behind the glove box and didn't see anything I thought might be this resistor/relay.

Thanks

pull the lower dash cover down, you will see it on the blower case.

I am having a similar problem but mine only works on level 4 and 5. Is this the resitor or something else.
