Heater Climate Control Unit fan switch failure?

Posted

It seems as though my fan switch has become a happy face Sad face type of fan switch.  It works on high only.  I suspect the switch may have failed.

 

I do have AC I do not have heated mirrors.  I believe the unit is P/N 55056702AD

 

If anyone has any other thoughts on why that would be awesome.

    Blower motor resistor(s) need replacement. Also, if the blower motor is drawing enough current to cook the resistors, you likely need a new blower motor as well, or you'll be replacing resistors again

    When you remove the blower motor you will see it on the left side or rear in the hvac box. Its pretty obvious once you are contorted under there. The part you linked looks right. I did not compare any

Yup, you need your vacuum pump on the engine twist to make vacuum to pull the doors open and closed. Yup, defaults to defroster... 

Okay so rookie lesson learned.  Now I know, no engine running, no vacuum pump pumping, no door heater/HVAC actuation.  Derp.

 

Thanks everyone.
