So I did some experimenting with this. I'm not sure exactly where to start troubleshooting for a fix. If I lift up on the door lock plunger, I can open the door from the outside, but not from the inside. It sounds to me like there is a combo problem with the action on the actuator arm at the latch assembly combined with a problem with the child safety switch. I don't know - I feel like I just made all that up. Should I just plan on replacing the latch assembly to fix? What could cause this kind of behavior that is actually fixable without replacing the latch assembly?

I found pulling the door lock, up and down, several times, unstuck my doors.

I tried this for hours. I think I just need to get the panel off and see if I can "see" something that is amiss. If not, replacing the latch assembly seems like the only other option.

After I manually worked, the lock plunger(top of panel, don't be gentle.), the doors opened. I sprayed the hell out of the latch with WD40. I gave the doors a couple of firm slams and hit power locks a few times.

Did this last night - it just needed to be lubed up but the child safety latch was binding. Couldn't really see back in there very good, but as soon as I got everything soaked down good and worked the lock and the child safety lock a lot, I was able to open from the inside and from the outside. I used WD40, but I probably should have used silicone spray. Thank you for all the insights you guys had. So extremely helpful.

Will open a new thread for recommendations on replacing the window switch housing that connects to the door panel - all tabs were busted off!

mine wouldn't open from the inside, i found the childlock switch to be gunked up/seized/jammed

after taking off the snap in cover, then spraying wd-40 liberally inside there thru the opening, then working the switch up down repeatedly, it totally freed up & then worked normal

however, the harder the door was then shut, or even after repeated door shuts, that alone could result in movement of the safety switch on its own into a lock position

so keeping that in mind has worked out so far,

never turned into or had an outside door latch issue,

good bet that original lube hardens & dries out then diff issues can play out,

i agree wd40 is best used just to free it up for temp use
