2002 Chevy Trailblazer Problems with heater controls
2002 CHEVROLET TRAILBLAZER
I have 5 speed controls for my heat and 1-4 don't blow out any heat but 5 blows out heat and I'm wondering what is wrong with it.
have the same problem?

It could be either your blower switch or the resistor. Yu need to check if the resistor is getting power in the lower speeds. YOu would need a test light and check eeach position as it will be low voltage and a dimmer light on each setting. It is by the blower motor and is a little square rectangular looking box. It's not very easy to change.
