Question type: Maintenance & Repair

Brake lights not working. My next step is the
ground wire. How easy is this to fix? Have
checked fuses and brake switch behind the
pedal. Top brake works, just not tail/brakes.
Any other suggestions? Thank you.

Check the bulbs? & look for wires (ground) that need to be cleaned up. Verify that there is power in the bulb socket with a simple test light. Brake switch is working if top middle break light comes on.

Could be the turn signal switch. Power for the outbound brake lights goes from the brake light switch, and through the turn signal switch. Power for the high mount (3rd) brake light does not go through the turn signal switch. It goes from the brake light switch directly to the bulb socket. HTH. -Jim

I was going to mention that the break lights to the rear lights are two different circuits. Start with the bulbs, ground wires, and then do you have power to the lights when the break peddle is applied. If not go forward towards the fuse. If you have power before the fuse, it may be the fuse or fuse connector. You can start from the fuse and go from there and work backwards. First is to buy new bulbs and replace them, cleaning the connections with emory paper to clean the contacts, then make sure the ground is clean and connected. If it does not work, power to the lights? Check the wire if you don't have power. Work forward a this time toward the fuse, or last place you have found power. Remember, the break peddle must be applied to send power through the electrical circuits.
