Well it's starting to get a bit colder here and i went to turn my heater on the other day..... the vehicle heats upto normal opperating temp. 100* so i turn my heater on full blast and it has a musty smell (like AC kind of, an dthe vehicle is completely dry inside so it's not musty from inside moisture) and the heat blowing from the vents is not very hot it's morelike a warm air. I have never had a vehicles ac compressor click in and out when the heater is running is this normal? I'm kind of stumped i am quite mechanicaly inclined but this one's got me. anybody out there having the same problem??
