When I reverse, error reads "Check Rear Lights/Brake Lights" and then car stalls out. When I roll electric windows, car either sputters or windows don't work, unless car is off and starter on they work very slowly. Top doesn't even budge when I try to put convertible top down. When I put heater/air on, car stalls quickly after even when I'm driving. Blinkers also cause car to sputter and they only work half the time.
