My brake system warning light does not illuminate when engine is started or when I have the parking brake on. I will tackle a lot of things but am always intimidated by electrical problems. I did take my dash out and checked the bulb and it appears to be good. It also seems like all the other dash lights work. Just hoping someone has had this problem and can learn something from their experience. I have a 97 TJ. My turn signal has occasion problems and my headlight switch also. They work pretty much just have to wiggle around sometimes. Just mentioned them in case they can be related to this problem.
