In high speed the resistor is bypassed and power is fed to the motor directly from the switch. Ditto what Mr. Stockman says. Join now! The highest blower speed usually bypasses the motor resistor completely, so it’s not a suspect if the motor doesn’t work at any speed. Run 12v right to the fan; if the fan spins with no problem, the control module is the problem. It is my understanding that at the highest fan speed, there is 0 ohms resistance upstream of the blower motor. While replacement is easy, the exact location of your blower motor fuse may vary from vehicle to vehicle. Didnt use to have that problem until I had to replace the blower motor resistor two years back. I have a 2001 GMC Denali.
