Hello, I'm Cam. Please include all the details about your issue so I can accurately advise you. I cannot see your vehicle so please be detailed.
Do you have a trailer plug installed?
yes a t style 9 pin
Check the wiring at the junction in the back for those lights, it sounds like the TEE may be shorted.
that solved that problem, now right side brake and turn bulbs dont light
OK, more wiring issues there? Do the hazards turn on?
yes except the right rear bulb. also there had been a trailer harness spliced directly into the system before the tee junction. most likely the problem is there, would it be a bad ground or a short in the circut?
It could be both so start testing. It could also be the turn signal switch.
