Burnt Wires - Why, and WTF is this?

Heater switch problem.

OK, I went to the local Jeep dealer and grabbed my new 3- switch panel.
It was only like $120 so not bad.

I was just about to put it in and find the problem here.

This little 3 wire adapter that is suppose to just plug into the selector switch was impossible to pull out. Why? Because it was burnt on there. So I remove the black rtape housing my wires and see that the Shiny greenn wire is completely fried!

Not the dull smaller green wire. I am pretty sure that one is the ground but the shiny almost metllic grn wire. Does anyone know what that controls?
Does anyone know what that whole 3-wire plug is for?
or how this could have happened?

Maybe I have to go back to the dealer to grab one of these 3 wire plug thingys and cut and splice it back into the wiring harnesss but it still doesnt help to tell me why...

Im confused.
here are some pics of what I am talking about...

That is a 12 gauge ground wire. The other 12 gauge is your fan relay. The small 16 or 18 gauge is your a/c control. In one of the other recent threads I posted how I just cut that thing off and spliced new tabs on. See if you can return that $120 unit, you don't need all that new stuff.

Hey Pokey,
Im glad you found me here in this thread! Thanx.

OK, First off I think I still have to keep that switch panel beause it looked like my first selector switch kinda melted...and this 3-wire adapter is melted on, so I will prob just have to cut the old one off for a re-splice onto a new one..If Jeep sells it...

right?

yeah, you probably would have still needed the climate control switch (make sure you get all those colored vacuum hoses hooked up in the same place). Sometimes I take a picture of stuff to make sure I get it put back together correctly. And don't throw the old control panel away, the fan switch is probably still good and they do go bad. You'll have a backup. Once hear your fan working again on all speeds it will be music to your ears

MARK your vacuum lines before you take them off........and THEN take you picture....I have used different color twist ties....or wire ties.....or colored tapes.
