Hot ac controls?

Hi today I noticed my ac control knob was feeling loose and upon inspection I noticed that the metal fan control that the plastic turn knob is attached to was hot to the touch.. almost hot enough to burn my finger? I turned off the ac and headed home to check it out,
-has anyone experienced this or have any ideas why it has become this way?

I just had the same issue (still working a/c issues with manufacturer) with my main brown connector for the ac being too hot to touch. it ended up being a factory terminal in the connection that was never a very good contact and had too much resistance in the connection to due corrosion or something.

too high of resistance in a connection is what you should be looking for. our ac systems rely heavily on 12v negative signals. check your switch wires with a multimeter for resistance on the ohm setting.

I now have the fan speed switch removed and it is damaged, the red wire in the 7 oclock position was broken ( from the rear view).. there is some small burn look to the wire terminal sleaves.. I am not sure yet if this was caused by the fan switch becoming loose and then grounding or touching the other wires..
does anyone know where to get a new fan switch?
it says across the top of the back (INDAK)
I will check RN tomorrow..

I located the switch and part # and will be ordering one today, I have the option of using the steel with zinc coating like the origional or a copper post?
