Power Locks, etc, malfunction
 

Suddenly, my tachometer, clock and power door locks quit working. It's pouring rain here, so I haven't been able to check the fuses. I wasn't all that worried about it until I went to the gas station tonight, and can't get my fuel door open. I can't get in my trunk either - could this be as simple as a fuse?
