2004 Chevrolet Trailblazer Q&A
2004 Chevrolet Trailblazer Question: My heater fan used to work on the 4 setting and now doesn't work at all. Any advice?
My heating/AC fan was working on the 4 setting and now doesnt work at all. I checked the 35 fuse under the hood and that was good. I also checked the HVAC fuses under the back seat as well. All good. I am wondering what the issue may be and the cost of repair. And if its the resistor behind the glove compartment, where exactly is that located. Thanks - ekk13
If you get no blower at any speed, check for voltage at the large lead going to the blower motor. I believe it would be purple on this vehicle. If you have voltage here, Check the ground wire. If both are good, the blower motor is bad. - Wilsonite
