Door lock issue (Not Actuators)

My power door locks just started acting up. The driver's side switch will not do anything. The passenger's side switch will lock both doors, but it will not unlock them. Is this a switch issue or the actuator? I am assuming the issue is on the drivers side only and am leaning towards the drivers side switch. With that said, I read about a lot of issues with actuators on these truck which makes me think it may be the actuator? Would the doors still lock if the actuator was toast? If it would, why doesn't the driver's side switch work? Anyone have any info on this? Thanks!

I subscribed as I'm having similar issues. On my truck, both driver and passenger switches will unlock all doors but neither will lock any doors. I don't have any of the weird lock/unlock/lock/etc. that I have read about so I don't think it's the body control module on my truck.

Edit: I know it's not my actuators because when the resistor inside the actuator goes out (which is what happens most of the time) they will still try to go up and down but aren't strong enough to fully actuate.

I know that's not the problem on my truck as I have done that on one door just to make sure and it changes nothing. I don't think that is blue72s problem either as his will lock but not unlock. From what I have seen when the actuator goes down it affects both locking and unlocking.

Then take the switches out and clean all of the contacts. I haven't tried opening up a switch yet, but if you can do that and clean off the contact points, that would be great too.

My contacts are clean inside and out. I got a wiring diagram for the door locks, I'm going to see what happens when I jump hot to lock wires after work.

The door lock fuse blows every time I jump from hot to lock on my truck so I guess I just have to decide if I want to take the time to find my short.

Replaced the actuator just to see if it changed anything, no luck. Contacts look good on the switch, I don't understand why the driver's side will do nothing but the passenger side will only lock the doors. Tried swapping the switches for the hell of it but no change.

Anyone have an idea how I can test the wiring or the switch?
