hey guys, i have a 95 and the problem is with the drivers side door....it will open likes it brand new using either interior or exterior handle.....but then an hour later nothing!! i pull either handle and the door doesnt engage....i push the locking mechanism in and out, yank on the door a little and finally it works but in the last few days it has been getting worse. harder to correct the problem! is it something sticking that needs lube or is it something that only catches when it wants to? thanks
