Silverado Blowing Door Lock Fuse

[woolyman2]

I have a 99 silverado 1500 4x4 z71 new body style with 225,000 miles and all of a sudden it started blowing the door lock fuse. It doesn't matter if you use the remote or either door switch, the fuse blows. Luckily it blew in the unlock position, but this is scary when I park in town. Any ideas where to start on the troubleshooting?

Sounds like a stuck actuator in one of the doors. I'd try unplugging them one at a time to see if the fuse stops popping. When it does, you found the bad one.
