The problem manifested slowly, over time missing only occasionally on the unlock/engage handle for the rear door. Now it does it constantly.
I can crawl into the back and push the little emergency access lever to the bottom in the rear door access panel and then open the door from outside but this gets somewhat more challenging when the car is full of groceries or plants or dogs and kids.
The rear door latch is tight and not the problem. The door locks OK but the door lock actuator isn't pulling the lever down far enough each time. I took the door panel off and lubricated all the parts I could find. This fixed the problem for about a month. I would replace the electrical actuator but I can't find a part number for it or a replacement on the 'net. I guess I could try and pull the thing out and open it up to lubricate the guts.
Anyone else have this problem? Oh yeah, the rear door glass wouldn't open either but that was because the cable clip was detached from the lock. I think it's a result of the door lock being semi-disengaged when the glass was opened.
Thanks for any input (and great forum BTW)
