[jaj28]

i bought a 02 ga gt about 4 months ago no problems untill now i was driving my car and it just shut off i have power to every thing but the car would not start poped the hood checked the fuse block saw that the ignition switch fuse was blown replaced it turned the key it blew again replaced the fuse multiple times and they just keep blowing i thought it might be my alarm/car starter so unhooked the moduals put a nother fuse in and the car started and ran a whole half a day hit a pothole in the road and guess what the car shut off and blew the fuse again now my local shop charged me $200 to tell me they dont know what the problem is plus went through 15 fuses they all blow out if its a short could it be any wire or hopfully just one specific wire any help woud be greatly appreciated
