Fan will not blow air. Exspect on setting 5 is there a fuse for the blower !! On a Sierra 2003 1500 extended Cab LE pickup

Answers from the Automotive Experts

Amanda J. Pierce, MBA Mike,, This may be a blower motor control failing, the resistors on the blower motor control could be worn and need replacement.

Lori Johnson, Owner and Instructor at Ladies Start Your Engines Dear Mike, Sounds like the blower motor resister. You should be able to replace this yourself once you know where it's located. It may be inside under the passenger dash. Lori Johnson
