Heater motor will not come on unless unless plastic housing in front passenger legs is smacked with a hammer. Once running it will only run on high. Switch down to med or low it stays on high. If you turn it on off using the the slide lever it may or maynot come back on unless it gets a smack with a hammer. Also when on high working like it should it all of a sudden will lose rpm, then smack it again it will pick up rpm to high. I'm thinking its the resistor. Any thoughts and if so where is the resistor located. <img src="/forums/images/graemlins/confused.gif" alt="" />
