I have a 94 Jetta, and whenever I hit my brakes my tail lights go dim. I can't use my turn signals when the brake is applied either. Also, the two turn signal lights in the dash light up when the brakes are applied. Ive had this problem periodicaly since i bought the car with 125K, but it always fixed itself after a few days...not so lucky this time. I did a bit of research and it appears its a faulty brake light switch is the cause, does that sound right? My cruise control has never worked either, which isnt a huge deal, but it looked to me like it plugged into there.
