2014: dash and rear lights stopped working. Had to replace multi-function switch. Module and wiring melted and fused together. 2017: during install of new stereo, mechanic discovered multi-function switch and module melted again. Replaced all wiring with heavier gauge, replaced all bulbs with lower wattage leds. Wondering when next electrical problem will surface.
Key switch spindle went bad, had to replace key, then had to replace the complete key spindle and the wiring harness, it started to short out and cause a fire. Had to go to the dealership for repairs, cost $ 2087. 00 dollars.
Had been noticing a plastic burning smell for a couple months, never found a cause or anything not working properly. Driving home early one morning I noticed my headlights were not working, the brights worked and so did the fog lights, but no low beams. After looking on Jeep forums and noticing a lot of people were having the same problem I decided to take the cover off my column and take a look. The wiring harness connected to my multifunction switch was burnt, proof of at least one small electrical fire, if not multiple small fires. I cannot be the only one with this problem, multiple posters on Jeep forums have reported similar events.
Have had ongoing electrical issues beginning in August, 2010. Check engine lights that have been proven inaccurate. Have replaced fan motor resistor x 2, electrical control unit x1, fan blower x1. Wiring is melted (burnt) at locations indicating fuse system/ wiring harness is not functioning properly.
Wiring overheating and melting blower motor fan switch at 36,500 miles. Wiring overheating and melting multifunction switch for turn signals, headlamps, hazards, etc. . . At 37,800 miles. Unknown cause for either failure. Replaced blower motor control switch assembly after failure myself as it was only $25 usd and 10 minutes time. Now the multifunction switch is doing the same - melting and causing headlamps to fail. Is there a voltage control problem with the electrical systems to cause these failures? will the replaced parts fail again? will a fire result the next time? updated 02-01-08 updated 02/01/08.
