Your going to have to try and crawl in there and get to the lock mechanism itself. If it doesn't open with the emergency release cable its going to be a pain. Obviously its jammed up somehow, to free it up without damaging anything will be a struggle. A long screwdriver with some pressure in the right spot on the lock itself while a assistant operates the release may do the trick.

Do you own a Power Probe, test light or multimeter? Please write back and let me know what tests you have run and what you have found so far. Most of these circuits are wired so they receive power when the key is in the ACC or RUN position and are activated from the Ground side.

May need new actuator. Try a slight lubricant like wd40 if that does not work. Try working switch back and forth. They usually start having problems when they get this old.
