Intermittent Blower Motor
My girlfriend's 2008 Cobalt has recently had an intermittent blower motor problem. Usually it works, but occasionally (once or twice) it does not blow any air on any speed. I figured I'd wait until it finally died before replacing it.
Today while we were riding along, the blower seemed to get pretty weak, almost as if the alternator was acting up. When this happened, the car was filled with an ozone smell. After a few seconds the blower motor started working like normal again and the ozone smell went away. I felt the wire going into the blower motor and it was VERY hot, too hot to comfortably touch.
So my question - has anyone else run into this? Maybe it's normal for the blower power wire to get so hot, but I doubt it. I know that electronics + ozone smell = fire, so the A/C is off until further notice. Is this going to be fixed with a simple blower motor replacement, and if so, what's the best bang for your buck on a replacement brand that will last awhile?
Edit: After doing some more research, it sounds more like the blower motor resistor. Usually when this happens you lose settings 1-3 but 4 works, but sometimes it can take out all of them. Any input on this? Thanks guys.
