replaced stoplight switch
Replaced stop light switch three times in a month problem was fixed for a few days each time. No brake lights again fourth time in a month changed switch still no brake lights. What else could it be?
The issue occured as I was trying to remove an aftermarket sound system from the dash and had to start the car and put it in gear to clear the shifter, then I shut the car off in gear with my foot on the brake. Then the code popped up! ODB2 apparently won't clear it and I'm locked out of my trunk so I can't disconnect my battery either, bad car week :-\
