Fan blower motor is on all the time.

Hi, my name is Devin. I am an auto repair expert with the Car Genius team here at RepairPal. I’m sorry to hear you're having trouble with your vehicle. If your Wrangler's fan blower motor runs continuously, even when the switch is off, and replacing the resistor didn't fix it, the issue might be with the control switch itself. If the control switch is faulty, it might not be sending the correct signals to the blower motor. Since the fan automatically goes to high when you change the climate setting, it suggests there might be an electrical issue in the control circuit. Checking the switch and it's circuits for faults might point you in the right direction. If you need more advice, have any other questions about your vehicle, or would like to get connected to a RepairPal Certified shop near you, we have you covered.
