Hi guys,

First post here. I have an '07 H2 SUT and the left marker light in the rear bumper is not working properly. It works fine as a running light when the headlights are on but whenever I step on the brakes, use the turn signal, or turn on hazards, it does not brighten or flash. I replaced the bulb and checked the fuse box and cannot find anything wrong. I replaced the working fixture from the right side to the left and got the same result.

If anyone has any advice on what/where to check, I would be most grateful.

Thanks in advance,
Jonny
