Door Lock Mechanism
Ever since I bought the car this has Pi$$ed me off. I hit Lock on my driver side door and the pass side locks perfect , but the driver side just budges a sec and thats it. I always have to close it manually. Any Suggs? I've taken off the panel and evertyhign and everything looks good but it wont work. Think the little motor is bad or what ever moves it?

Mkos,
The lock solenoid is where you should be concetrating. The coils don't last forever, and the core can bind in the solenoid, preventing full actuation. A little wear in the linkage rods, a little swelling of the coil, and before you know it the locks will "click" but not operate. All the wear in the linkages is additive, so operate the solenoid core by hand while you observe the linkages all the way to the lock plate. I'll bet you'll find some wear and binding.

A slight trace of very light oil on all pivot points will help greatly and on the solenoid plunger shaft if you can get to it. I have had good luck repairing these locks in a different area too.
The plastic slide, where you actually put your fingers to lock the door, is a slide type lever that resides in a groove. All is well when the part is new but after 10 years or so the slide grooves and slide lever take on the consistency of 80 grit sand paper sliding up against each other.
Much pressure can be relieved by dressing the edges down on the button slide and coating it with white lithium grease on the edges, then install it back in the track and work it back and forth a few times.
