Repairing headlight switch that causes dimming issues *picture heavy*
If your jeep's lighted cluster/vic/hvac controls are dimming by themselves, it's probably due to bad solder joints on the headlight switch. I fixed mine yesterday and took some pics and added in instructions. This was done on a 97 Limited with auto headlights and fogs.
soldering iron that goes to 600-800 degrees farenheit.
SNIPERDUDE! I just did this, and first of you instructions were spot on, AND it worked like a charm. In your other thread you spoke about "bending" where the two pieces meet. I had no idea what you were talking about until I disassembled my switch and sure enough, there was a lot of "bending". Once I resoldered the points there was no more "bending", and sure enough it works like new. This solved my problems with the Auto Headlights and the lights on my guages flickering. Thanks for the help!
Thanks for this great post, Sniperdude. I'd have just thrown out my part without doing the repair that you recommend. And it worked perfectly. To your excellent advice, I would just add one item for those with soldering experience. When "resoldering," you should always reheat with new solder. This helps fluxing and also acts as a bit of a heat sink.
if your dash lights are flickering up and down, you can clean the sliding contact switch with PB Blaster. it is a great electrical connection cleaner.
You got to spray it into the slider past the plastic dust flap and work the slider back and forth.
For some reason, my GC 1998 has numerous little electrical connection failures. Switches, sockets, wiring plugs stop working due to all i can guess high resistance corrosion. It is not visible when you look at the metal, but it is there.
for example radio connection plugs in back of radio, abs connection plug for rear wheel sensors under the dash, dash lamp sockets, headlamp switch, turn signal bulbs.
Just did mine! All the instructions were great, I had some trouble getting the panel out, but that was just me. Anyway, its all fixed now, thanks for the pictures!
