im sure someone knows were to find the wiring diagram or maybe you can tell me why my AC fan **** only turns the fan on when i put it to high, none of the other settings work (low - med etc..) i was told it was a relay and it probably is but...and maybe you could tell me how to know if im on internal air or outside air?
Thanks

 

Standard climate control, or EATC (electronic temp control)

Most likely the blower resistor mounted into the heater/AC plenum next to the fan blower.. The internal 'thermal limiter' burns out and the only setting that remains is the high position/function...

 

Thanks
its regular ac control.

theres no ***** or buttons or indicators to switch from inside air to outside air. eerrrrrrr. im assumimng one of the ac control positions is inside air.
