2000 chevy S10

Well this started last week if you step on the brake you get one brite and one dim so i thought ground, clean all grounds. and now step on brake and revisre light come on HELP AND THANKS Jim

Somewhere you have a short to power. Most likely you have 2 wires crossing so that when you hit the brakes and power is sent to the brake lights, it is also sent to the reverse lights.

A short to power can be a tricky thing to find.

I had a problem similiar to this and it was caused by an aftermarket inline trailer plug adapter. It had a pin in the wrong place causing a short.

Yeah my vote would be a trailer adapter of a short in the wiring back near the tail lights I'd start there look for burn spots in the wires where 2 may cross or bare wiring... I hate wiring on vehicals sorry I can't help more.

no trailer plug, but i will look for some bare wire's. the day i got the truck the wife backed in to one of them little yellow poll's she said i didn't see it bang!!. dead center in the bumper ok sure dear didn't see it thanks jim

lol yeah if there's no plug then I'd be looking for crossed wires... Did she do damage when she backed into the pole? That could've jarred something under the bumper which is where the wires for the tail lights are located.

yeah i would definitly have to agrea with the short or pinched wire... they run right along the drivers frame rail.. there are many places for them to get beat up though so i would start at suspected tail light and go down the line.. good luck.. electric is a nightmare with these trucks..
