Man it's been a while since I've been on here (had to create a new account).

My 90 YJ has been sitting for about 7 years. Trying to get it up and running again. Here's the deal. I have no brake lights. The bulbs are fine (they work for tail lights and turn signals). The fuses are fine. I replaced the brake light switch but that didn't help. Thoughts?
 
Grab a multimeter and start seeing where you have power and where you don't have power. The brake light circuit is very simple, so it should be easy to track down. For example, do you have power at the connector for the brake light switch, etc..
 
Turn signal switch may be at fault. If it's wired like GM turn/tail, the brake lights run through the TSS. Or you have a bad brake switch or mice got into the wiring. Test light is your friend for sure.
