Have a 2003 Chevy Venture. Over the weekend I noticed the fan operates only on low regardless of where the speed is set and it will not shut off either. The rear controls work fine and have full spped control, but the front only runs on the lowest speed. Is this a resistor issue or is there something else I should be looking into?
If it were a resistor issue, you would still be able to get the high fan speed. But since you can only get the low speed and doesn’t turn off, it points more to the fan speed selector switch.

I appreciate the suggestion - I will get the multi-meter out and check that switch tonight
