No brake lights on one side

I am not getting any brake lights our turn signals on the passenger side tail light. I only have parking lights. Its not the bulbs. Any ideas I don't want to get harassed or rear ended. Thanks guys.

Hey Tim

Keeping working your way back till you find voltage. I would guess it is not the wiring. Socket? Grounds? I know you know it, but the light bulbs have two filaments, one for parking and the other for brakes and directionals.

I changed the bulbs so I know they are good. I don't think its a socket because two went out at the same time.

Not sure how the set up on sedans are, but won't the tail lights get screwy if the 3rd brake light switch is dirty? Or am I talking out my rear?

Check fuse 13, also Justin is right about the high mount brake light, but it would affect both sides I would think. Make sure it's a 2057 bulb and NOT an 1157. Also the high mount needs to be a 2357. Does the arrow on the dash come on and stay on when you put the right blinkers on? Or does it come on and blink?

I always use 1157 with no problems. I don't have a third light I removed it to install a custom speaker board. The turn signal indicator stays solid.

Idk I thought 2057's have different locking tabs. The 1157s will no doubt light up, but may rattle loose over time and maybe your not getting a good enough connection. Also what happened to the wires/socket from the high mount? Are they shorting out the system? I wanna say that there's a harness connector under the rear bumper skin that connects the left to the right tail light wiring harnesses but not 100% on that and also if your getting parking lights I can't see it being a wire problem. How abou tue flashed unit for the turns (not the one for hazards) oh and check to see if the hazards flash!!! Might help narrow it down.

After studying an exterior lighting wire diagram I've narrowed it down to a possible worn out turn signal switch. The parking lights get their signal from the headlight switch. The brake lights/turn signal filament gets its signal from the turn signal switch which has its own separate left and right circuits. That would explain why it only failed on one side.

I've got the same thing going on with my RMW right now. I'm hoping it is just the bulb.
