I am wondering if the rheostat switch for the fan speed on the heater is defective. I cannot shut it off, even when the ignition is turned off. I have to remove the fuse to have it stop. I also have no control over how fast the fan runs. My truck has a digital display for the heater control. Thanks for any help you have.
