Question about 2003 GMC Sierra

Blower motor works intermittenly & I smell burning wires

I bought the truck this spring and occasionally I have smelled burning wires. Over the last 3 weeks the blower motor has quit working on me several times. If I wiggle the pigtail connection at the resistor it will start working again until it happens again. The connection seems to be very hot. I purchased a resistor pack and replaced it and it hasn’t made any difference. It appears the pigtail requires replacement as the third connector is burnt out. I talked to the previous owner recently and she advised me she had problems with the connection at the blower motor resistor and had it replace. Is this a common problem and what is the “proper fix” for it.

    What should the amperage draw on a new motor be? This way I can confirm that mine draws too much. It hasn't blown the fuze yet.

Burning smell

Sounds like there is an electrical problem. Its probably in the ac / heat system. I would suspect the blower motor resistor or blower motor is going bad.

My 2001 grand marquis heater turns on but wont blow i smelled a strange smell before it quit

Could have been the resistor or the blower motor. It was probably a burning wire smell.
Check the blower motor for power and ground.

The heater fan either makes noise, or today it only worked on high and had a smell to it, do i need to replace it?

This is definitely (based on works on Hi only) the Blower Motor Resistor located near the Blower Motor. It is defined with 3-4 wires going into it. It is easy to remove and replace. Purchase the part at the auto parts store versus at the dealer to save you a lot of money.
Install this first before deciding to replace the Motor.
After reinstalling, if the motor is making noise, turn it off IMMEDIATELY so you don't burn the resistor up again. The smell should be either the Resistor burning-up or the Motor burning out. The smell should have an odor like electrical burning?
Let me know if this helped, or if you have additional informatin or questions. Feel free to contact me on!

Aircon works fine for 5 min after starting car then funny smell and nothing but warm air. when revs kept low might come on again for few min

Check the compressor when you notice the smell. See if its running or not. It could also be the blower motor itself. I'd suggest checking the blower motor first off. Those usually only last a few years, and if it got wet some how it could have rusted or corroded on the inside. Or a wire broke on the inside and it shorts out to ground which could explain the smell.

Heater not working

The problem is probably the blower motor resistor. I'm not sure where yours is located exactly. They can be on the firewall under the hood or some are near the blower motor under the dash.
