For the last 3 years, I've had a grounding problem on my 1999 TJ Sport. For the first 20 minutes, no problem. After some jostling around, when the brake pedal is pressed, the left turn signal lights up on the dash and front fender (turn signal stalk is in neutral position). I had a trailer harness installed 9 years ago, but I removed it and it still didn't help. I also replaced the turn signal generator, but that didn't help either. I've traced some of the wiring out and wiggled it trying to reproduce it, but nothing. I've taken all the bulbs out and inspected them and put electrical grease in the sockets, but still nothing.
I've gone a little nuts trying to chase this ground! Can anyone help or have any ideas?
