Before writing this I scoured Comanche Club to see if any MJ owners have had this same issue. After much searching I've found some posts with similar problems, but not exact matches. In my instrument cluster, the LEFT Turn Signal Indicator sometimes works (and) sometimes it doesn't. It's quite finicky and annoying to not see blinking. Probably 40% of the time it illuminates, while 60% it remains dark. - Replaced both front end Turn Signal sockets & bulbs - Replaced both front end Side Marker sockets & bulbs - Replaced every bulb in the Tail Lights - Turn signal Flasher is NEW - All exterior lights function properly - All fuses are NEW and none are blown - TURN B/U fuse terminals feel nice and tight - Cleaned the fuse block with QD® Electronic Cleaner & Canned Air Nearly every Tail Light socket had serious corrosion (the old front Turn Signals did as well). Had to use precision pliers, PB Blaster and a heat gun to work out each of the broken bulbs. Was a real mess. All exterior bulbs now have dialectic grease. Below is what I thought of doing to get the indicator working properly: • Clean up instrument panel ground below the dash • Remove instrument cluster to clean and/or replace blinker light sockets & bulbs • Separate and clean out that wire connector behind the driver's headlight Am I on the right track to resolve this issue? Or would you guys recommend trying something else?

Ok guys, I have a slight (well hopefully slight) issue with my instrument cluster lights overall illumination and a couple of other things... Just some background, the entire harness inside and out is from a '90 XJ Laredo. I followed a write-up on here about mating the XJ's dash harness to the MJ's rear harness for the fuel pump and brake/tail lights. Those work flawlessly. The engine starts and the brakes/tails work. Anyway, the issue is the illumination for the HVAC panel, the instrument cluster and the clock light doesn't work with the parking lights or head lights on. Also, the turn signal indicators glow when the parking lights/head lights are on. The driver side turn signal indicator glows brighter than the passenger indicator. The turn signals do work but not the hazards. It's like some current is being back-fed or something. Fuses are good, all the connectors have been thoroughly cleaned with electrical contact cleaner. Grounds are good I'm fairly certain. The tach, temperature, gas and oil pressure gauges all work. Dome lights work but not when you turn the head light switch all the way over counter-clockwise... Anyway, I'm thinking faulty head light switch, as everything I mentioned above runs through that, correct?
