| Brake Light problems |
The wipers do not always work. There seems to be a short of some kind in the system. I can get them to work by manually moving them sometimes. Also I'm having a problem with the brake lights working. I have replaced the tail light assembly twice. Again it seems to be a short in the system, they work on and off, its very dangerous.
