My car heater works, but not on the highest setting. It only works on the first three levels, but not the high setting which leads to me having to wait forever for it to warm up in the winter. Any suggestions on how to fix this?

Hi
Either the switch is bad or there is a problem with the blower motor resister. With the switch on high, check for power to the resister. If it's getting power, replace the resister. If there is no power, go to the switch and check if there is power out when on hi.

Let me know what you find.
