GMC Blower Motor \

[Craftman1221]

If any one can help me I would appreciate it. I thought the blower motor on my '92 GMC went out so I replaced it. It still is not working the heater it self works. Is there a relay fuse or something I may be missing. Thanks for the input.....

Sounds like a resistor...

Make sure you know if you have a resistor pack, or if you have a solid state blower motor control module. My 2003 Silverado has the automatic dual climate control, and when I had a similar problem, it was the contol module (the truck does not have the resistor pack like the manual temp control units do). It's a simple fix: 4 screws, unplug two sets of wires, do the reverse to install -- 10 minute fix). The part for the 03 Silverado is 89018778 at gmpartsdirect.com; the AC Delco part number is 15-80567 There may be a different part / number for your vehicle.
