On my car, one of the door switches for the courtesy lights had dirty contacts. Even with the door closed all day, the switch would become VERY hot. While this didn't drain my battery, I imagine that 2 switches doing this at the same time might just be able to blow a fuse. To clean I just removed the switch, and sanded the contacts with some really fine sandpaper. While this may not nessisarily be the exact cause of your problem, it is something that you should look into. -Robert vin 6585 --- In dmcnews@xxxx, "Adam Price" <acprice1@xxxx> wrote: > > Hello I recently bought a delorean and have discovered an annoying problem. > I noticed my courtesies lights were off one day so checked the fuse and it > was blown.
