XxStirCrazedxX Posted March 11, 2012 Share Posted March 11, 2012 Ok this must be a common prob, when I press the brake all my lights inside the cab turn on, my 86 2.5 5 speed did it, and the 87 4.0 5 speed that I picked up also does it, anyone else have the same problem if so how did you fix it? I'll take a vid and post it up here in a bit. Link to comment Share on other sites More sharing options...

ftpiercecracker1 Posted March 12, 2012 Share Posted March 12, 2012 you must be grounding out the system some how. Do your tail lights come on when you hit your brakes? Link to comment Share on other sites More sharing options...

JeffN Posted March 12, 2012 Share Posted March 12, 2012 you have a ground problem somewhere Link to comment Share on other sites More sharing options...
cruiser54 Posted March 12, 2012 Share Posted March 12, 2012 Brake lights are searching for ground. Remove your left taillamp and check the ground wire. Remove it, scrape the paint off, polish up the terminal and reattach securely. Gotta start somewhere. XJs and MJs all suffered from a poorly and underdesigned ground system. Easy to fix and costs under $20 and an hours time. Link to comment Share on other sites More sharing options...

XxStirCrazedxX Posted March 12, 2012 Author Share Posted March 12, 2012 So i disconnected the turn signal switch and now my dash lights don't come on when i hit the brakes, I can't tell if my brake lights work till my wife gets home from work tho. I'm sure they should still work, but ya never know. Went ahead and cleaned the ground behind the tail light sence I was out there and it wasn't that bad, looks as if the PO knew about the ground issue. Will keep you updated, thanks guys :) Link to comment Share on other sites More sharing options...
