inside the door's locking mechanism is a series of rods, clips, levers, and pivot points. most likely, there's some binding, and everything needs cleaned and lubricated. looks complicated, but it's really kind of simple. everything inside probably needs serviced. about the only way to address this is to remove the door panels to gain access to everything, and have fun!

But I would just pop out the silder first by putting a small screwdriver under it and prying it off. Then clean and lub there. Then spray a bit of lube down the rod working it back and forth. Might save you from pulling your door pad.

dry lube, like silicon

the internal rods, etc, gathers dirt in the grease over time, turning it to a sticky near-glue, so a good cleaning and light relube with white grease may be in order. When I do such, I also attend to the other moving parts, like the window mechanism.

had the door panels off everything looked good but I did not lube/oil anything since everything seem free and worked ok with the panels off. I was wondering if it could the power door actuators make be not enough power to push or pull the rod? why would it be both doors?

Might just be sticky on the plastic slide from 20 years of crap. And clean the ele conections and test for voltage.

then, there's your problem - installing the door panel.

look at the rod that attaches to the sliding lock button as it pokes through the door panel - look for any binding and look for any interference between the rod and the sound deadening pad - you may have to do some minor trimming to the foam. something's putting the "squeeze" on the rod - there's some interference in there somewhere. good luck - keep us posted -

the alignment of the rod and the slider can be an issue and doesn't 'feel' right on assembly, nor work properly, as the OP describes.
