Hey guys. I've had this issue on my car since 1994. It's street legal but only hits the road a couple of times a year. It's usually just trailered to the track. Anyway, my brake lights rarely come on together. It's usually just one or the other. It all depends on how you move the turn signal wand. If you wiggle the turn signal wand around while pressing on the brake, the brake lights will take turns blinking. If you find the sweet spot where both lights come on together and hold it perfectly still, the brake lights work correctly. If you are off a micron, it goes back to one light. I thought it was my old turnsignal switch wearing out so I put a brand new unit in there and it's the same story. Is my car wired wrong or is this a common problem?? ANY input is greatly appreciated!!!
