Question about 2002 Chevrolet TrailBlazer
If you have auto climate control, replace the blower motor controle module.
If you have Manual climate control, replace the blower motor resistor assembly.
Both are in the same place, on the bottom of the blower motor itself. Take off the plastic kick piece at the bottom of the glovebox to access the bottom. You'll see small screws holding the piece to the blower motor. From there, empty your glovebox and open it. You'll see an access hole to the left, stick you finger in there and depress the spring loaded piece to drop the door upside down. There you'll have access to the electrical connector from the blower resistor to the blower motor. Very easy job and is a very very common thing to go bad.
