Power door locks don't work
 

Does anyone know how to fix this problem? I can only manually lock them which is annoying since you have to lock the back doors from the inside.

Thanks

Do you mean from the remote?

no, I mean from the key. Shouldn't the drivers and passenger locks, lock everything when I turn the key? That's what I was told and that's how my volvo works. Any ideas? It's a 95 Disco btw.

Thanks

Your door lock actuators are bad.
Sit in the truck with the key off and close the doors, push the drivers lock down, do the other work?
The drivers lock is the master control for the others.
It is very possible that they are all bad, but start with the drivers door first.

none of them work.... only bad actuators would do this? Is there something that controls this system?

Yes, the drivers door controls the system.
