In my 88 vert I inconsistently get the brake lamp warning. I used to get it all the time and found that that issue was the 3rd brake light and fixed that issue by wiring around it. No it stays off most of the time but occasionally comes on only when I turn the right blinker on. Have the right bulbs installed and all connections are good so kinda stumped. Anyone have this problem before?

The Check Circuit that was mentioned will be mounted behind the rear seat side panel on the drivers side. check to make sure all of the wires are clipped in properly, and maybe ziptie the plugs in.sigpic

No, on verts it's not behind the seat, it's in the third brake light, which he's already bypassed. Dunno man, check your grounds? Try to find Luke's thread as FLG suggested, he talks about cleaning the ground connection inside the tail bulb holder. When I was tracking mine down, I actually couldn't clean mine, i couldn't pull the connectors apart, but maybe it will be easier on yours.'89 lachssilber vert - Frau Blücher

The logic of the brake warning light is the AND of power to the circuit and all three current sensors. If the result is true, the LED turns off. If false it turns on. The power up state of the logic is for the LED to be on, which is why you have to step on the brake after starting the car.
Since the OP stated that the right turn signal can activate the warning, the only logical explanation is a wiring problem that is allowing at least some power to reach the brake circuit. If that leakage is insufficient to allow full current flow, the LED will turn on.The car makes it possible, but the driver makes it happen.

(as opposed to next to the antenna on a coupe) This panel may have a bad connection or be broken and causing the check panel to light up.'89 lachssilber vert - Frau Blücher
