Question Door locks quit all at once

Anyone have an Idea about why both door lock just went flat out dead all of a sudden. 1999 F150 Is there a fues that controles these? I bought the truck without a owners manual otherwise I'd check it out for myself. If one goes bad would it effect both of them? Thanks first timmer

I would check your fuses. And you can download an owners manual, or buy one. I downloaded one cuz I tend to be a little cheap!

The lock relay fuse is located in the battery junction box under the hood (driver's side) not in the cab. It's the #8 fuse which is 15 amp.

The door lock actuators on 99's are notorious for going out and it's not unusual for them to fail within a short time of one another.
