Jeep Wrangler Brake Lights Q. Hi, I have a 1988 Jeep Wrangler. It has a 4.2 liter engine, it's a manual, it's got 117,000 miles on it. I have a question, okay my brake lights don't work, my tail lights work, but not my brake lights, and I check the fuses, they are all good and I changed the brake switch and still nothing, what else could it be?

A. I'm assuming you have power at the brake light switch.

Power goes from the brake light switch to the turn signal/hazard switch. If this switch is bad then the brake lights won't work.

To check this, step on the brake and see if you have power at the yellow and dark green wire on the switch side of the connector. If you don't, check for power at the white wire on the switch side of the connector. If you have power there, then the turn signal/hazard switch is indeed bad.
