Help! after a search i couldn't find a thread on this problem so here goes. my daughter has an 09 Cobalt LS that blows the ignition fuse when the key is turned to start every couple weeks. i have replaced the starter, ignition switch, swapped the relay and the dealer has replaced the under hood fuse block.now it has started blowing the fuse constantly. luckily it was in the driveway when this started. when the ignition relay is unplugged from the under hood block it doesn't blow.any advice would be greatly appreciated.
