In your fuse block, there might be a bad circuit breaker, they are the metal covered blocks that plug into the fuse block. Look for a small rectangle shaped piece about 1 inch long by 1/4 inch wide. They plug in just like a fuse. If your fuse block has more than one of these, try swapping the positions of them.If you have the owners manual look in it for the fuse block locations-look for one marked main, acc or ignition. Hope this helps, electrical problems are a real pain.
