1989 BMW 535i. My A/C went out a year ago and was living without it until 6 months later my heat went out. I replaced the "sword" resistor and 1 month after it stopped working again. There is heat but no blowing. I took it back to the place that replaced the resistor. They said the blower motor has enough amperage. And they "said" the resistor was ok but maybe the module on the resistor could of went, but they said they couldn't test it. I don't understand about the module on the resistor or if it is testable. Does nayone have any suggestions or guidance for me on what to do. I live in Wisconsin and it is -20 degrees today. I also want to mention that I have a lot of electrical problem with my car as well. I need to repair or replace my LKM (I think) my tailight and parkin glight on same side doesn't work and I know its not the bulb, just want to make sure I am doing the right thing here. Does anyone have any LKM's for sale.

Thanks
