the fuse that controlls the cig lighter and driver's seat keeps blowing out. when I looked online to see which fuse I needed to replace it said that a 20 watt fuse was supposed to make these work. When I opened the hood I found a 30 watt fuse in that place so I just replaced it with another 30 watt fuse. Now it seems like I have to replace it every other day. plus I think that fuse is what makes the door make that beeping noise when it's ajar and that beeping goes off at random times (like when the door is shut). Is there maybe a short that is over working the fuse?? please help... i'm pretty mechanically challenged
