1989 cruise control causes brake light problem
I had a 1989 Jeep Cherokee XJ (downsize, not FSJ) that had the same yellow cruise control module as my current Grand Wagoneer. I had that XJ for 25 years. One problem that came up when it was about 20 years old was that the brake lights were on and wouldn't turn off. When I traced the circuit for the brake lights, I found that the brake light wiring went through the cruise control module (presumably to turn off the cruise control when hitting the brakes). I opened up the module and found a burnt section of the circuit board that was shorting out. I was able to repair it and fix the brake lights and the cruise control.
Since the cruise module was being discussed, I thought that I would mention this in case it might help someone at some point.
