My wife has a '04 Passat. Today, she parked it and we noticed the rear rights and 3rd brake light is on, even with the car off. I wasn't sure if this is some type of indicator of a bad bulb, bad fuse, or a brake pedal switch.
I pulled fuses until the lights went out. Turned out #13 (picture of a light within a circle) was the one controlling it. I don't have an owners manual but, guessing it might be a brake light switch as someone already said. Where is the brake light switch and can someone enlighten me on what I need to do to change it? Do auto parts stores carry it?
