2001 Bonneville SE brake and reverse lights

Unread post by StefonRobinson » Sun Aug 25, 2013 5:20 pm

When I brake the reverse light lights up along with the brake lights. What could that be?

wow, that is a weird one. has anyone changed light bulbs or done anything with the wiring? brakes light and reverse light are different systems. Reverse goes through (should go through) neutral safety switch to the PCM then to the rear integration module then to the reverse lamp relay. Comes out on the light green wire to the bulbs. the brake light goes from the stop lamp 15A fuse to the brake switch then white wire at the brake bulbs. Check if you have power at the light green wire to the reverse light when you step on the brake. If you do start check the wiring back from there. Has anyone put a trailer wiring connector on this car? BTW, does putting the car in reverse turn on the reverse lights? And the brake lights too?
