I Have a 03 chevy silverado 1500 and the blower motor is not working. The blower motor is good and It has a brand new resistor. I am getting power to the red wire on the resistor but no power to anything else. I also replaced the a/c switches and have checked all the fuses and relays. The blower wasnt working when I bought the truck. I also dont think the blend door motor is working but it is also getting power to one of the wires. when i turn either of the ***** on the switches nothing happens and the switches are good. Idk where to look now. Any suggestions will be helpfull thanks

 

You may need to test/ replace the HVAC control module.

Try this first.
