So my motor/switch had been working only on high for about a year then quit totally so I replaced the motor resistor like it says in all the other forums, but now:
Blower works on settings 1-2-3 but not 4(high).
Also, sometimes when I start the engine and the switch is already in the 3 position(where I leave it) then it is not blowing at all and I have to flip the switch back and forth a few times before it starts blowing...
Is this the switch unit ? or maybe the motor itself ?
