Ok so i got an alarm installed about a month ago and i remember the installer telling me that he had to tap into my powerlock wire because the drivers side door always said it was open so the alarm would malfunction. So my car was fine for 2 weeks and now all of a sudden my radio, powerlock, and lighter fuse keeps blowing (all are on the same fuse). When the fuse blows, my alarm keychain always tells me that the door is "open". This means that it is also relating to alarm. So what can i do about this? Can it just be wires touching each other because the car was fine for 2 weeks and now the fuse blows every day. Any suggestions would be appreciated, thanks.
