Hey guys I got an 03 prix and the heater blows hot but recently has been acting funny, it will blow like it's on 5 than blow likes its on 3 and will fluctuate between the two, before the heat would only blow if you put the switch to the 3 setting, it wouldn't work on 1 or 2 but 3,4,an 5 did work fine so I didn't care till now...i was thinking of just replacing the the whole unit but if anyone else has had problems with this plz chime in, I'd hate to buy a new dash unit and it not be the problem, oh and the clock display doesn't work either. Thanks guys
