I have a 98 that has been running good since I bought her about 8 months ago. About two weeks ago all of a sudden the heater fan stopped blowing except on the highest level
. Positions on the dial one, two, and three do not turn on the fan like they should, only the 4th dial (or 100%) will work.
Previously when it started getting cold and I was using the heater a lot I noticed a burning smell coming out of the vents, it smelled like burning electrical wire but it was entirely sporadic and only lasted 5 or so seconds on my 30 minutes commute. Also my alternator recently failed but I doubt that would have anything to do with it as I replaced that only a few days ago.
I was wondering if anyone else has had this problem and where I could start looking for a solution. Not sure if its a simple dial failure or the whole unit. Its about 10 degrees here in Michigan so I'm not using the lower settings obviously but if there are exposed wires in there, I'd like to get them repaired.
