the heater blower resistor located in a 2001 gmc sierra?

The blower motor resistor on a 2001 GMC Sierra is typically located behind the glove box. However, the exact location can vary slightly depending on the trim level and specific model.

To find it, you'll likely need to:

1. Remove the glove box: This usually involves removing a few screws or clips holding it in place. Consult your owner's manual for specific instructions.

2. Look behind the glove box: The resistor is often a small, rectangular or square-shaped unit attached to the HVAC system's ducting. It may have wires connected to it and might be clipped or screwed in place.

Important Note: Before attempting any repair, disconnect the negative battery terminal to prevent electrical shocks. If you're not comfortable working on your vehicle's electrical system, it's best to take it to a qualified mechanic.
