My brake light comes on once in a while, with part of the electricity system not functioning, such as windshield wiper does not work. After restarting the engine, the brake light goes off and the electricity system works again.
Hi, I have a 2002 Cabrio with 19,000 original miles on it. I am having a problem with the lights in the instrument panel. When the headlights are on, some of the panel lights are on and some on and some go on and off when they want. The clock and how many miles I have on the Cabrio are lit all the time. The speedometer and the other 3 panels are dark, intermittently. Can the bulbs be replaced? Does the entire instrument panel need to be replaced?
