HELP: No Drivers Side Brake Light
(2000 2 Door 4x4 Blazer) First off, thank you for your help, secondly; I want the reader to know that I have both turn signals and right brake light working. No it is not my bulb, I have replaced that. Maybe some fuse, relay, or im missing a ground somewhere?

Welcome to the forum. The first part I check when I have brake light problems is the brake switch by the pedal.

Check the fuses. I think there are two separate fuses for the Brake lights. If it was the brake pedal switch, it would affect both left and right side brake lights.

Sorry for the late reply, what would they be labeled? And would it be in the fuse box or interior fuses or in like the firewall/ stereo area. I know their is a control block as well I havent replaced under the bumper..

If I correctly understand your problem:
Left turn signal works as it should
Right turn signal works as it should
Right brake light works as it should
Left brake light is NOT working
I would suggest to roll it up from the light fixture forward.
I'd try to jumper the left brake light ground first, then the PLUS in order to determine that the fixture itself is working correctly.
I'm not sure about the U.S. brake-turn lights. Is it the very same bulb with only one filament or does it have two separate bulbs or a two filament bulb?
That would be my first analysis. Just make sure the fixture is working. Then move forward from there.
