Now I apologize for yet another door stuck thread, but I've read so many door lock actuator threads and door handle carrier threads that my head is spinning. Between the different symptoms and andrewwynn's wonderful, though super hard to understand what's going on without parts in your hand, pictures and tips I'm lost.
From what I gather, the double lock portion of my left rear door lock actuator is dying.
Or, did the system just get confused due to the battery condition below. Looking for confirmation.
Symptoms/conditions:
1. Never had an issue until recently when the truck has been seeing
extremely dead battery cycles (3v on one instance
) due to vestigial EHCII module draw.
2. Left rear door would not open from inside or outside handles.
3. Key fob (or lock cylinder) will pop up/retract the door lock pin on top of the card 100% of the time.
4. Could hear cable being pulled when manipulating either handle.
5. Outside handle does not feel spongy and opens the door without being pulled up excessively far/hard.
I tried the double lock emergency egress procedure and could hear the locks pop but still could not use inside/outside handle to open. Worried child lock was engaged as we used to haul the kids in Red. Tried that procedure a couple of times. No luck. Then, figured I'd use the key in the door lock cylinder to lock/unlock repeatedly and feel for any change while manipulating (just manipulating, nothing violent) the inside rear left door handle (windows are down obviously). After a short time I felt a "tug" and voila. Both inside and outside handles now function as they are supposed to. Visually verified child lock was not engaged (obviously as the inner handle ultimately opened the door).
Only tried lock/unlock with fob a handful of times since but everything works as it should now. Was something just out of sync because of the battery situation? Or am I sitting on a time bomb of double lock actuator failure? I believe I remember seeing a coding to disable double lock from single press of FOB? Can anyone confirm? Will look into that.
As always thanks all.
