Rear markers..

[Chevyrider619]

Any one know what can i look for after my r/r marker went out, it aint the bulb's. The revers bulb works but stop and r/t marker dont. I even switched all the bulbs from the left and still they dont work.. any help would be appreciated.

It might also be the tail marker circuit board went out???

I had two circuit boards go out on me. Turns out that the last guy put in some trailer wiring and cause some issues back there. I took it out before I put in my new rear lights.

mine magically did the same trick. I had brake lights and turn signals replaced boards and still didnt work. I cut out the splice uhaul trailer wiring from previous owner and now have lights it was a bad ground. only problem is my pass side brake lights go crazy when I apply the brakes. So I traced all the stock grounds cleaned them and put copper washers front and back. Now lights work fine brakes work fine but when I turn on the lights the pass brake light is still F'd up. So more tracing. Point of this is you have a bad ground somewhere spliced trailer wiring is a good place to start.

Alarm was also part of my original problem. I was a POS add on. But we gave you an awesome heads up on what is wrong that is the best place too start no other magic bullet to fix it just got to get dirty and look at the grounds and good luck, I got all my problems fixed except no interior lights.

ok fellows the rt tail light is WORKING wuwwwwww!.. I just kept messing and messing with it. So i think its the plug or bad ground cause if u wiggle it, it wants to turn off, HATE ELECTRICAL problems! but yea it stays on.. Just my reverse bulb is not, i traded from the l/t tail and nothing so gonna buy bulbs and i guess chk the ground and plug..
