Door lock issue

[truck]

The driver side door only locks and unlocks manually from the inside. The passenger side only locks by using the key from the outside, exact opposite of the driver side. I just bought the truck and I need to get this fixed. Any ideas?

Thanks gentlemen!

did this happen all at once ?

It's a 96, and I just bought the truck that had the issue already so I wouldn't know. I just found out the passenger side door lock button will lock/unlock the driver side door, but will not lock/unlock the passenger side. The driver side door lock button will not lock/unlock either door, but the button works (I hear and see the locks moving but won't lock/unlock) ...wtf

I have to hold mine down for a second for my drivers side to lock.

On the drivers side it sounds like the linkage from the key lock to the locking mechanism in the door in disconnected, probably a broken clip. Electronically speaking the locks are controlled by the BCM, might wanna check connections on it and check for proper voltage at both switches. Try to find a wiring schematic for the switch to check. Could also just be more clips are broken and making the locks twitch as the bar moves around.

I have some wiring schematics at home I can check later. Thinking about it, I'm not 100% on the BCM thing, but I can let you know if no one else beats me to it.

No BCM looks like.

Thank you for sharing this information. I will be taking apart the doors later today... I appreciate it!

Open your door and pull back the boot covering the wiring.

It is common for the wires inside to fatigue over the years and break after 20-odd years of open/close cycles.

Mine was like that, several others here have had the same experience.

If that's the case what would I do to fix this
