not sure why the fuse blows but aside from the obvious of electronic door locks will only unlock manually. it causes the key to be stuck in the ignition, the car to be stuck in park, and the car won't stop running... just replaced the fuse today. popped it in and it worked. got home 1/2 hour later problem started again... don't really want to keep a higher amp fuse in there due to possible fire... but its kinda a paper weight right now with out it
