Door lock issues

[neev_nav]

Hey everyone.

Been having an issue with my power door locks on my 94 K1500 for a while, and I finally have been trying to tackle it. Here's the scoop.

The drivers side power door lock switch does nothing. No lock, no unlock. The pass side switch only has unlock capabilities, no lock. The pass side will unlock both doors. I have swapped in different switches with no luck, so I figure it is not a switch issue.

My question is where to go from here? Is it possible that both actuators went out? Or is it more likely a wiring issue?

I have a wiring diagram, but I am having trouble making sense of it. The way I see it, the power runs from the convenience centre, to the drivers switch, then to the pass switch, then to both actuators. Is this right?

Any help would be appreciated.
