I need to replace a blower motor to my 2006 gmc sierra

Check for voltage on the fan itself- if the voltage is there then the fan motor could have cause the resistors to overheat due to it's drawing too much current. Oil the bearings with Tri Flow oil and they will spin much better- the trouble is you need to get the fan out to service it.
You can oil and recondition the Commutator and renew the fan if the brushes are not worn out if you have it on the bench.

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

This is your blower motor regulator. It is under the glove box and behind the blower motor itself. They are cheap to purchase but a pain in the rear side to replace. Hope this can help you out sir.

could be the blower motor relay orthe blower motor resistor

I would get the fan motor itself checked out. #5 position is where the current goes straight to the motor, that being burnt out indicates a burnt motor to me, or the resistor is fried. But I think the resistor is either in the motor or the controller, so either way, do check the fan.

if you do not hear the blower motor blowing it is possible. If it moves air but isn't cold the it would be in the compressor but if it doesn't move air at all id be inclined to say that yes it is the blower motor.

very common, ive done many. replace the blower motor resistor module, located next to blower motor and also plugs into blower, follow the wire from blower to resistor, heres apicture to help, napa auto parts sells this part,its about $50.00.hope this is helpful.

There is an updated resistor/connector package. Very expensive from GM, try your local NAPA or other parts supplier for a replacement

blower motor may need to be
replaced
