when i try to unlock or lock the truck using the remote, only one door listens and unlocks or locks.

I can hear slight movement on each door but they dont actual lock/unlock.

If i try to unlock from the door control switch same deal. I can go and unlock/lock each door manually but i cant do this with the remote or the switch on the driver side.

Can anybody tell me if this is the door lock actuators failing or something else?

 

door lock actuator has failed. there is a vendor on this site who makes replacements...search the vendor directory. here is the site https://www.gruvenparts.com/

 

make sure you try to protect your car using protective barriers from outside thieves as well!
