Yesterday my blower motor did something very strange. It only blows on High
(4) also when the AC button is pushed in, it (the ac) shuts off when the
fan is set to high. The AC stays "on" on 1 thru 3 but no air flow exists.
Do I need to look at replacing the blower motor?
Thanks in advance
If your blower motor works on High then the blower motor works, it is most probably a wiring problem, so I would advise checking the switch if it works and then all of the connections from your switch to the blower.
