Right side brake and reverse light out, swapped bulbs, still out?

[dmojim]

Can anyone tell me what (and how to) check next? I had 60k service in mid september, followed by (minor) body work to the right rear quarter panel. Everything was fine for a few weeks and then last week the "check right brake light" warning came on. I got a new bulb, which did not work AND then in addition to check brake warning it also displayed "check reversing light". I moved the original"bad" brake bulb to the left, and the left to the right--the left worked and the right was still out, so it is not the bulb. could the body shop have disconnected wiring and re-connected something wrong that would take a few weeks to cause this???

both the left and rear brake lights are stamped 1057. PEP boys did not have that model, but they pointed me to a P21 bulb--anyway, the left works, and the right 1057 is not bad since it works fine in the left side. Not sure what to try next.

Thanks for input/guidance

Sounds like a bad ground or damaged wire on that side.

Inspect the wiring and the sockets for damage or corrosion.

thanks Loren

I see no damage, and the contacts looked fine, i cleaned them anyway, but while the reversing light message on the dash is gone, the brake light message remains, and when i hit the pedal, the left and 3rd brake light go on, but the right remains off. One thing i did notice is where the wiring harness plugs into the taillight assembly, the left has 6 wires, the right only 5. This can't be anything new though, the lights were fine until last week.

Possible blown fuse?

i checked the brake and reverse light fuses, which per the diagram is row A fuse 6 and 7, both are intact. Is there something that just would feed the Right brake light but not the left and 3rd?

The left brake light is operated directly from the brake pedal switch, the right and 3rd brake light is operated via rear control box (ROW - LHD). I would check the wiring from the tail to, and the rear control box itself to start with.
