My headlights, wipers, heat/AC, and convertible top won't work...need to get the electrical issue resolved.
turn signals stop working when I press brakes.
Trunk light comes on, while trunk is shut. Radio won't work if truck light is on. Continuously blowing fuse for inside lights.
Alarm went off by itself which resulted in trunk light on and wont go out even when trunk is closed, radio has no power to it and wont turn on, blinking red alarm light on inside door lock not blinking when I lock the door, inside door lock/unlock buttons are not working when pressed.
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.
Began with CD player, mounted R. Rear; then r. f. running light, now R.Rear tail light; clearly electrical.Fuses check out fine.
There is no power to driver side door
Dash, dome light and rear licence plate remain lit and will not shut off.
Signals, cigarette lighter, dash lights, door locks by key or button on dash, headlights, high & low beams.
we just had the same problem, however we have noticed it only happens when it rains.

The Lights will flicker in the cluster panel and the fuel pump starts to prime on a constant basis until you put the key in the ignition and try to fire it up. at that point you get nothing.
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?
