stop warning light problem
Ok I got a weired problem. Sometimes when I step on the brakes the stop warning light turnes on. But this is rare.
It's almost a guarantee that the stop warning light will turn on:
1) When I FIRST step on the brakes and THEN turn on the signals (left/right) the stop warning starts blinking. But the front and rear signals are working fine. I don't think that the parking lights on the fenders should be blinking.
2) When I FIRST step on the break pedal and THEN put into reverse (auto transmission). But the reverse lights work.
3) The stop warning light sometimes turns on when I FIRST step on the brake and then move the sun/moon roof front and back. The sun/moon roof works fine.
thanks

But all the brake lights still work. All the rear brake lights light up when I step on the brakes. Is it possible that when ever I do the actions I stated above they could be messing with the brake light(s)?

Okay I checked the grounds to the lights (the black wires right?) and they all seem like they are in good condition. But what I haven't checked is which part of the body it ground to.
The farthest that I've followed the grounding wires was a little bit past the antenna. Anyone know where the wires end up?

^ I didn't do any S4 to S5 conversion. I just replaced the bulbs with an OEM replacement from Shucks to check if that would solve the problem. But it didn't, now I think it really is a grounding issue. But I just don't why because as far as I can tell the wires look fine.
I guess I could try regrounding the major parts in my car (like battery terminal, engine block to firewall, etc.). But I still think that shouldnt be necessary for me to do in order to solve the this problem.
thanks for the help.

well on the S4 the Brake warning is the 4 pin plug/board on the bottom of the CPU. They almost never fail. But I do have rebuilt ones on my webstore if you need one.
