Crazy power lock problem

All of my power locks (except for the drivers side which doesnt power lock anymore) are making a loud clicking noise and look like they are trying to either lock or unlock over and over again. The only way it will stop is if i pull the Elec. fuse (the Ctsy, fuse doesnt stop it). Once the Elec. fuse is pulled the locks work fine, as does everything else except my headunit (a Eclipse 5425) which wont turn on. This just started happening all of a sudden. Its not always constant, some doors will stop, or go slower, and then faster. It happens when the car is running, on acc. or off. If I hold down the lock button it will stop. Also the locks will no longer auto-lock when the car is put into gear. Possible the relay for the auto-locks is screwed up? This is the only thing I can think of. Its a 93 Lumina. Any help would be much appreciated.

yes, or you have a bad switch.
