Having problems with your 2003 Chevrolet Tahoe ?
2003 tahoe blower motor run after truck shut off also speed dont change
You have a defective blower motor resistor. You need to buy a new one, I recommend from a dealer because the part quality and warranty is better. Remove the lower plastic on the passenger side bottom of dash. It is a large black plastic cover retained by 3 7mm headed screws. Once the cover is removed you will see a round item sticking out of the very bottom of the black plastic heater box under the dash. You will see a 2 wire connector plugged into it. disconnect it. follow the 2 wires back to the resistor which is a small rectangular box retained by 2 gold screws and has another 6 or 7 wire connector plugged into it. remove the connector, and two screws, and it should pull out. Reverse the procedure to install.
