Brake light issue. At a loss

[springbok]

I am having an issue with my drivers side brake light. The right one works fine but the left one is very dim. I replaced the light switch to start. No luck. I tried 3 different LED tail lights. Same thing. Turn signal works fine. Hazard light works fine. Just the brake light. I tested the trailer plug and plug B (left brake light) looked to have 24v. Any ideas???

Have you removed grounds and cleaned and remounted.

Replaced all ground wire ends just to be safe. The stumper here is turn and flashers are bright. Just the brake light function is dim.

And it's just that one or both.
Maybe a bad light all together.

Turn signal switch.

Would I still get power to the trailer plug if it was the turn signal switch?

oops, you already did what I suggested.

Only getting 6V at the light when I hit the brake(only on left side). Turn signal works fine. I changed the turn signal switch. Nothing. Jumped the brake switch. Nothing. Any ideas.

What voltage before the light.
See if your losing the volts before the light or in the light.

After checking the trailer plug I get 6v there also. Was dark last night so my mistake. I am really at a loss I guess I have to trace it all the way back to the turn signal switch

The same 461 wire goes to the turn signal control that powers the same bulb for brake and turn.

Fixed. Seems that the turn signal lever was bad and to make the newer type of lever to work you have to remove the bulb and put in an LED one. Ahhhhhh thanks for everyone's help.

Your very welcome sir. I do believe NDT gets the gold star. He said turn signal switch.
