Heater blower motor question.... - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Tonight I installed the new heater control unit that included a new switch to replace the old broken one, plus a new resister (just cause it was cheap). Before, and now, when the switch was in low, your could just barely hear the motor turn, on medium it sounded like low should, and high was somewhat close to what high should be.

I am getting good voltage to the switch. It's it possible that the motor is bad? I know it kind of sounds obvious, 'specially since it is all that is left, but I figured the motor would either work or not.

BTW, this is a non-A/C truck. Thanks for any ideas!
