Heat & Air Fan on 2004 Chevrolet Silverado 2500 HD

The fan is turned up as high as it will go but will not blow air. I can feel cool and hot air but barely. What would cause this? Blower motor?

If no blower,, under the pass. side of the dash beside of the blower motor is the resistor, wiggle the wires going to it with key on and blower on hi. If fan tries to start you have your hand on the problem! Replace resistor and the wire connector, dealer has best price and OE parts. This will fix 99.9% of this type problem.

the squril cage on the blower motor more than likely came off.
