Why don't my brake lights and tail lights don't work but turn signals do on a 1988 Jeep Comanche?

If your brake lights and tail lights aren't working while the turn signals function normally, the issue could be due to a blown fuse, a faulty brake light switch, or a bad connection in the wiring. The turn signals operate on a different circuit than the brake and tail lights, which is why they still work. Check the fuse box for any blown fuses, and inspect the brake light switch located at the brake pedal for proper function. Additionally, examine the wiring and connections for any signs of damage or corrosion.
