The demand lighting fuse which is slot 25 in the passenger fuse box is causing the car to not start at all and it won’t even crank. When I take out the fuse the car is completely fine. I know that it might control the trunk light because when the problem started the trunk light had melted and the whole connection was just a mess. First of all I want to know what demand lighting does besides control the trunk light and if it’s important. I also want to know any solutions to this problem so I can put in a fuse and be able to start the car. I figured I could just put in the fuse while the car is running to see what would happen but I obviously don’t want to risk ruining anything else over a minor problem I just want to get it fixed before I sell the car. Anyone know what could be the problem?
