The blower motor in my 2005 GMC Sierra won't turn

Wiring problem of the 2005 GMC Sierra 1500 6 Failure Date: 07/18/2009

The connector that plugs into the blower motor under the glove box became too hot and melted the plastic resulting in the a/c and heat not to work (this includes the windshield defroster). I've been looking up problems and solutions and found that this is a recurring problem with GMC and chevy trucks yet there has not been any recall, in fact the dealerships have an extremely overpriced kit to fix their faulty wiring. About 66,000 mi.

Get a new swich

resistor block open circuit

My fan motor quit working. Is there a site I can get pictures and instructions to replace myself. Thanks.

replace the blower motor resistor located on the passenger side under the dash around the blower motor

The blower motor resistor is a common to fail and cause your problem. It is located on the passenger side on the underside of the dash. There are two screws that hold it in and very simple to replace. Check the wiring and connectors that go to it. There is an udated version that you can buy if you notice any burnt look to it. The other wires go to the heater motor and will need to be unplugged. Just reinstall the new one and give it a shot.

You need to replace the blower motor resistor module.It is located on the passengers side by the blower motor.There is a bulletin for this problem.I`m not sure if you an get one at any part store.If not you will have to get one at the dealership.Hope this helps.Good luck.

did you check the fuses and did the motor come with a new heater resistor or is it separate

blower motor resistor is burnt out on those speeds

sounds like the blower motor resistor is bad. it's located on the passenger side under the dash behind the blower motor itself. Just changed mine on my 2004 sierra. Fairly easy job to do. Hope this helps :)
