We left Saturday morning, to do some camping over the New Year's weekend. When we left, all four door locks on the dually were working fine. When we got to the campground, I hit the unlock button to let the dogs out of the back seat and the passenger side rear was still locked. I hit the button on the remote and learned that the only electric lock still working was the passenger side front.


To make things even worse, I cannot even unlock the passenger rear by hand. Both driver's side doors can be locked/unlocked by hand.


Any ideas?

 

It could be the master door lock switch, but it is weird that you can't unlock them by hand. Maybe disconnect and reconnect the switch on your door panel, and see where that takes you. Do the same for the passenger side, just in case there's something weird going on there that's affecting everything.

If it were only one door, then I'd say it's one of your actuators, but with a bunch at once, it could be the fuse or the switch causing it.

 

I'm really not sure what's going on.

Both door lock switches work, but only on the passenger-front door.

The only door that cannot be unlocked by hand, is the passenger-rear. All three other doors can be locked and unlocked manually (Without using the switches)

 

Nevermind....I had my hands in motion before I got my brain in gear.

 

you might want to pull door panel off the one that you cant manually unlock possible linkage problem

 

forgot to mention electric door lock actuators can be short lived i had to replace all four on used truck i purchased

 

I have to get the door open, before I can pull the panel off. I haven't figured out how to get it open yet..
