Fan Speed Irregularity
Fan speeds 1 (low) and 2 (med) run just fine but the minute I switch it to 3 (high), it slows down significantly and hardly seems to be moving any air. My first thought was maybe the heat load was too high (I live in southern Mississippi) but I've tried it on 55deg mornings and have had little luck getting it to come on.
Each speed worked great about a week ago and one day going to start the car in the morning it wouldn't kick on. Anyone have any insight? Low/med speeds blow cold air just fine so I'm at a bit of a loss. Same issue occurs when trying to run the heater. Thanks in advance.
