    I own a 04 gmc canyon 3.5 ltr offroad model. My blower motor does the same thing and what My problem was it that GM did some Sh*tty designs on this model.When passenger adjust thier feet especially in winter when people are in boots the unknowingly hit the connector with the blow wires and the get loose.if you look you'll see a harnes with 4 diff colors each is a different setting.If you try wiggling them around you may find your problem and fix it with electrical tape as i did

Ac fan speed


Replace the blower motor resister,this is the speeds for the blower motor,it is located very near the blower motor,and is mounted on the blower box,and it actually goes inside the box,to keep it cool.The reason for it`s failure is the blower motor,even though the blower motor sounds,and runs good,it is drawing too many amps.If this was at all helpful,please rate,thank you.

You may have 2 separate problems, check the bower motor resistor first, if it's bad replace it and THEN you should have the fan blowing on the lower settings.

If the ac turns on after you fix this then problem solved, if not it may be unrelated have a pro look at the ac.

The AC blows on #4 fan setting but doesn't blow at all on 1-3


That is the blower resistor. 4 is wide open, so, no resistance. I had 4 of them put into my truck. The wires were burnt and shorted the others until the problem was found. Check the plug if you do this yourself.

2003 AC unit problems


there is a resistor block in the blower housing, it could have been damaged when the field mouse nested on the blower.

it is coils of wire ( nichrome wires) with 4 wires connected to a socket . this slows down the speed of the motor.

tnx 4 using fixya,
