Fried A/C speed switch w/pics!

I have been having issues with these for years now and am fed up. This time it wasnt just the resistor pack which went out two months ago. Now I started smelling burning plastic when running the a/c on high. The a/c only works on high now. The buttons to the fan and a/c/heater had some heat damage last winter, they melted and had to be glued back on.

Now I discovered that on the back of the a/c panel in the dash the connector from the wiring harness is melted onto one of the copper prongs from the switch. The switch now has a big melted hole in place of this connection. Here are the pics.





What should I do about the melted connection on the wiring harness? replace or can I cut it off and put metal tabs on that hook to the new switch? New switch and new resistor a must obviously, how about putting in a relay is that necessary like on jpmag site? I dont know if I can figure that one out. Thanks for the help!

I am off to the stealer ship tomorrow to try for a resistor pack and a switch, but dont know about the harness side of the switch, its pretty burnt up!!!

I just swapped the speed switch on mine as well, i had no 3 speed setting. Now all the settings work but the a/c just shuts off now and then and i have to give it a smack on the side and it comes back on. I think i have some kinda loose connection to fix now. Im tired of it to be honest!!!

Screw JEEP, Mopar, dodge, chrysler, This is a problem which they have neglected for over 5 years now!!!! Why isnt there a recall of the wiring harness?? They are cheap and we know this is a bad design which fails every time over a year now!!! They should fix this or pay? Class Action lawsuit anyone??? THis is dangerous, fire?? Geeze! How can I see black smoke inside my cab today and think that I am safe driving a JEEP? I cannot!!!! This is a major problem which they have known about for years and have decided not to fix!!! We should file a class action lawsuit to get them to fix this BEFORE SOMEBODY DIES because their faulty designers screwed up. I am sure there has been fires started among the public because of this. I alone have had to smell these noxious fumes for the past month! THIS IS A SAFETY RECALL AND THEY KNOW IT AND ARE NOT DOING ANYTHING ABOUT IT!

*NEWSFLASH*
It's not just a Chrysler problem. It happens on Chevys, Fords, and other vehicles, too. If you want to make sure it never happens again, cut the plug off the harness and solder the wires directly to the switch. No more resistance from bad connections, no more heat buildup.

Seriously its probably the switch contacts are a bit too small causing the heat build up.Soldering the wires on wouldn't solve that problem,if you really want to fix it forever use the switch to operate a small power relay.NO more switch problems.

I have never had this issue with any other vehicle I have owned nor had I heard of any of my friends having it. I buy a jeep and had to replace the resistor pack right off.

Can you post some directions on how to do somthing like this. I live in Vegas and its 112 today. My a/c cut off and even banging on the side doesnt make it turn back on anymore. Im taking it apart as soon as the sun goes down to see where the problem is. Im ready to put a toggle switch under the dash or somthing just so i have relaible a/c the rest of the summer.

I dont see how that solves the problem of the melted harness plug? I cant drive till its fixed, what do I do buy crimp connectors or try to solder it? I have a propane torch might be able to solder it with that, just kidding, but dont have a soldering pen either....

Well if you want to do a quickie basic job get a SPDT 12 vdc 30 amp power relay and use the switch to turn the relay oh.When the relay is not powered you would use that path to run the low speed( or what ever speed you like best while driving) resistor to the fan.When you power the relay the relay contacts would provide full speed power to the fan.

Its so freakin simple i just saw a Republican do it!
