Question about 2003 GMC Sierra
Hello: Under the passenger side of the dash on the bottom of the heater case you will see the blower motor and the blower motor module, check the six wire connector and see if there are any burned wires, if there are Chevy/Gm have a harness you can buy and replace the burned part. Also the module may be burned, if so replace it to. Hope this will help you.

Could be a bad switch, blower motor, resistor or bad ground/wiring problem....test for power at the motor and a good ground with switch and ignition on to see if power is getting through and go from there. Some import cars wire the circuit backwards which is the power is sent to the motor first and the grounding circuit goes through the resistor and fan switch.

I had the same problem and Ia m working to resolve it.
You need to remove the blover under the glove box it's very easy to remove. 1) remove the glove box, 2) the metalic suport that it's hold by 4 screws and finally remove the 3 screws that holds the blower. Take it off and remove the coverplate of the motor ( 2 screws) and
check the brushes. In my case they were worn out. So you need to buy a new motor with the blower aprox $50 or try to replace the brushes.

Try a SHOCK test to the blower motor case. What I mean is SHOCK the case by hitting it with the palm of your hand (make sure you have the blower switch 'HIGH' and the IGN key also 'ON'.. if the blower starts working, you have an intermittent contact in the motor itself. If this doesn't work, get a test light and connect it to the connector that plugs into to the blower motor - if the test light illuminates, then the problem is obviously in the motor. If it doesn't, then you have a wiring/switch/power supply problem.

it will be hard to diagnose with out having my hands on it but try this.
this vehicle is known for blower motor resistor failure.
under the dash on the passenger side next to the blower motor there is a resistor attatched to the blower motor case it will have a single plug with 5 or 6 wires in it, they are normally within a couple of inches of the blower motor, remove this resistor and look at closely for any signs of burning this is a common problem, you can buy one at any parts house, do not operate the motor with the resistor removed from its mounting hole or you will damage it.
if the resistor looks good than purchase you a test light and drop me a line and i will explain how to test the entire system its not hard to do.
