Cannot open drivers side door using the inside door latch. Pull the latch and nothing happens. There is no problem opening the door from the outside. Even the power door locks work fine. I am thinking this may be a problem with the door latch cable. I took the door panel off to check it out . From a parts diagram I see the cable goes to the door lock/latch unit. I wanted to take the holding screws and bolt out but wasn't sure what would happen to latch assembly after that. I would appreciate any help diagnosing my problem and removing the latch assembly. I have maintained this car for 160K miles incl changing pwr wind regul. mirrows, braking system, minor engine and suspension work, so I am willing to try anything.
