Putting together the audio system today and figured I would take a look at the Heat/AC control unit to see why the a/c only works when I smack the unit sometimes and also to see why the fan control was so quirky at times. I knew the back of the plug for the fan control got pretty warm at times cause I could reach my hand in there and feel it as I have had the stereo out for a few months while I installed new door speakers and was adding a layer of second skin to the vehicle.
The control unit has been acting quirky for about 3 or so years now. Once I took it out I was amazed I didnt burn down my vehicle lol.
Attached are the pics of the fan control knob and its plug in. The whole knob just fell apart and the grease thats inside it has been cooked. The AC cutting out and working when I hit the unit can be attributed to a wire that came unsoldered and was barely touching two resistors inside the unit. It was coming off of one of the little blue covered bulbs inside.
Im just wondering if that wire touching caused that knob to burn out too? I highly doubt it. Can these knobs go bad? Is this a sign its bad? Can I reuse that plug when my new HVAC control unit arrives?
