Sorry for the repeat posting but I'm just not getting any answers. I'm hoping someone new might take a look.
My heat cuts on and off. At first I thought it was a bad switch so I replaced it. Now I see that the plastic port (connector) that hooks onto the control knob (the one that changes the air to feet, head, defogger etc.) is a little melted. When I give those wires a tug from within the glove box, it either comes on or cuts off. How do I go about replacing these wires and that connector? I don't know what it's called... or where the wires lead.
That sounds like the same place mine melted. The right hand switch that changes from vent to defrost, etc. I ended up taking the melted plug off and individually reconnecting each spade to the switch. A light tweak with needle nose pliers made sure everything was tight. A drop of solder may make it an even better connection.

Seriously? You can just connect the wires directlly? I'll have to look into that. I suppose I could take the plug and go to the dealer with it and see what they suggest. Does anyone know what this piece is called?
the dealer doesn't have it as just that one piece.....its part of a cluster of pieces that are like $200......and mine did the same exact thing that you are speaking of. as A2SuperCrew said.......just reconnect them......i think you actually need to break off the plastic connector that connects the ELECTRICAL wires.....(make sure you don't break the plastic on the connector with like 8 tubes....these are vacuum lines and you will hate yourself after if you break them) then you need to cut the very end of the burnt wires off and put your own spade connector on.....then just simply push them back onto the switch block.....it's actually SUPER easy once you see it up close with that melted connector off
I replaced the heater resistor and still had issues I found that the wiring harness at the heater itself can become loose because it is exposed to being kicked. And yes it gets very hot behind the dash. I have had issues with my jeep starting properly because of melted wires.
I would not put the connectors on without the black plastic clip. It keeps the wires sepperated and holds the wires on. You can clean the burnt plastic off the connectors and find another plastic clip at a salvage yard.
Although it may be part of a harness you can still go to the dealer and get just the connector. It certainly wouldnt hurt to see if it does come with the complete harness (meaning just the switch wiring). It could have a connector another foot or so further down the harness.
They have an entire book of just connectors so you get the correct one.
Once you get the correct one, get a couple as spares.
I got the black connector from a parts guy at a dealer in Lewisville, Texas. He said he has seen this connector melt on alot of Wranglers. He cuts them off of all the Wranglers he comes across in salvage years, gave me one for a twelve pack. I just sanded the melted plastic off the connectors and inserted them into the plastic connector he sold me. Another parts guy at the dealer said not to leave it on HIGH for very long after the cab gets warm. We'll see how long this last.
I looked this thread up to copy and paste for someone in another thread, the picture of the melted switch in post #6.
Thought I would report that my connector has not melted again so far. I only leave it on high for maybe 5 min max.
The #3 setting has gone out on the cheap *** switch, but I can push on it to get it working. If another setting goes out then I will replace it.
