My driver's door is difficult to open from the outside. When you pull up on the handle it does not seem to fully disengage. I tried putting lithium grease on the latch mechanism at the door jamb but it did not help. Something is not releasing completely when I pull up on the handle. I can still open the door but it takes more effort than normal. Anybody have experience with this, is it worn out, do I have to replace internal parts??

Wear in the handle mechanism. Sometimes the handle needs to be replaced, sometimes you can get by with a linkage adjustment. Remove the door panel, find the rod from the handle to the lock assembly. Lift the rod out of the cradle in the handle and disconect the spring, screw the barrel shaped device down toward the bottom of the door, 5 or 6 turns should do it. reinstall the rod and spring to the handle and try it. Should open easily now. If handle wear is excessive, replace it. New at dealer around 90.00. Go to junk yard and get one from a back door, they don't get as much wear. 76-93 will fit, but they are different left to right. Front to rear is the same.

My 80's been doing the same thing, only from the inside, for a while. Today I took the door panel off, gave the mechanism a pretty good squirt of wd-40 and now it works great.
