Interior Door Handle getting harder to open

Anyone have experience with their door handle getting harder and harder to pull to open? I know they're cable actuated, but whenever I look up anything about this, I can't find what I need. It feels like the cable is getting stuck(?) if that makes sense. It's happening on the driver's side, which obviously gets the most use.

Any help is appreciated!

 

I would think being 21+ years of use & if never lubed some cleaning & lube of all mechanism's & cable would be the 1st place I would start, couldn't hurt.

 

The door panel is easy to remove and look inside the actual door. You should be able to see if there is any issue inside.

 

wait until it breaks
