Power locks...'sorta' work
In my 93, I can't lock or unlock both doors with the button or key fob. The passenger side will UNlock with the key fob, and almost lock via the the switch. The driver's side lock tab on the inside will move a little, but it's more like a little nudge... It's just enough to tell me that there's juice in the system.
So I'm wondering if this stuff just gets gummed up and can be restored with some simple cleaning and lubrication, or do I have to buy some new parts?
I'm going to tear into it soon, I just figured I'd ask first. Thanks!

MOST likely, like most of C4's the little plastic slide with the red or grey (depending on year) indicator warps over time and gets bound up in the slide mechanism. If you doorpanel has EVER been off on the sticking side, the slide rod going to the slide was bent, almost 100% of the time that happens, Take the door panel off either way, bend the slide rod CAREFULLYto close in to the door, IF you bow the rod, it will be worse than it is now, its kinda of a trial error and is pain, but this is the usual suspect , either way, once the door panel is offer, you can test the lock actuator. its a 15 minute job if you have taken door panel off before and are familiar.
Good Luck!

Pull the door panels off and clean/lube all the moving parts of the lock system. Mine did the same thing, I cleaned it and it's all good now. I was amazed at how much dust build-up was behind the door panels.

I had the same problem. Cleaning and lubing didn't help.
My solenoids were "tired".
I bent up some new links about 1/4" shorter.
That was about 2 years ago. Locks are still working fine.
