1993 Saturn SL2 Power Door Locks on steroids

I have a 1993 Saturn SL2 with well over 200,000 miles on it. I love my little car and it runs great! However, it has started acting haunted as of late. My power door locks decide to try to lock adn unlock on their own. I can hear he mechanism going but the locks do not move. After it stops (by me holding the lock down for about 10-15 seconds) the manual locks are frozen and will not work at all. If I leave it that way for a few hours the locks usually loosen and can be locked manually. It has even gotten so bad that it ran my battery dead one time.

What is going on with my door locks? Do I need to pull the fuse for the power locks and call it good? I realize that this is an older car, adn things are bound to start falling to pieces around me, but am unsure as if this is a mjor fix-it or not. Help?
