I think I know the answer--I ruined it. My fan was working only on setting 4, so I got a blower motor resistor. It worked ok, but it took a few seconds on settings 1-3 for the fan to actually come on. If I turned it to 4 and then back down to one of the lower settings, it would blow right away. So maybe there was already something wrong with it. Here's where I think I ruined it, though. I didn't want to put it back in place and screw it in until I tested it out, but didn't notice that it was resting on a flashlight. After my next drive I saw that it had melted some of the plastic on the flashlight (like just about through to the battery compartment), and the next time I tried it it didn't work at all on settings 1-3. Still works on 4. So I'm thinking that it overheated because it was out of the fan path and/or because it was resting on the flashlight. So I obviously need a new resistor, but I'm wondering if I should get the blower motor as well. It occurs to me that maybe it was running too hot because the motor is on the way out, and had nothing to do with lying around on the flashlight, I have no idea how hot these things are supposed to get. The fan does make a kind of squealing noise when I first turn it on. When I was looking on the forum for a how-to on the resistor I believe I saw a post on how to check the motor, but I can't find it now. Any suggestions? Thanks in advance.
