Brake light/signal issues
I have a 97 TJ, automatic, with 94k-miles. When right signal is used, all three break lights flash, and when the break is applied, all three break lights come on as well as the front right signal lamp. This problem started when the top was left off during an unexpected rain...interior got very wet. It has been drying for 2 weeks now, and not correcting itself...any suggestions? Thanks!
It sounds like you have a grounding/shorting problem somewhere. I'd trace all the tail light wiring and make sure you don't have some bare wire grounding to the chassis or to another wire. Maybe a taped connection is holding water inside it...etc.

It is entirely possible that that soaking your jeep recieved, may have put some water into your turn signal switch. The current for your brake lights, initially, comes through your brake light switch, then into your steering column turn signal switch. When you apply the brakes the current flows through the brake switch then through the turn signal switch and on to the brake lights. When you turn a signal switch on the brake light circuit still flows through the switch but the signal is switched through the flasher unit on the side you have the switch turned to allowing the lights to flash. If the contacts inside the signal switch have contact to both the brake lites and the right turn, you will get exactly what is hapenning, the contacts for the right turn would be lower in the switch than the contacts for the left turn, it would not take much moisture to cause this. You might be able to use air pressure to blow out the moisture, but in the worst case you may need to replace the turn signal switch etc.
Thanks for the info, I played with the switch, and didn't have any luck with getting it to work right. After replacing the multifunction switch (signal switch) with a new unit ($58 from dealer) it is working like a dream. Very easy to replace, by removing 8 screws and two wire harnesses! Thanks for the help!
