A few questions-
When you hit the switch or remote, do you hear a click from the locks? Actually, if you listen carefully, you'll hear two clicks, about a second apart, when you lock or unlock. If you don't hear a click, then the problem may be the console switch. THis is unlikely, because both the switch and the remote don't work well.
The central locking box sends a 1 second pulse to the door lock actuators. If the actuators actually move, you hear a loud click. If they don't, you should at least hear a quiet set of clicks.
It could be a bad ground at the controller box, a bad set of contacts in the relay inside the controller box, or one actuator may be pulling too much current.
For the first, quickest check, go to the CL box (up under the left side of the instrument panel) and pull the connector off, and put it back on a few times. That will clean the contacts. See if that fixes the problem.
There is a connector on each door frame, and the lock actuators go through there. All the actuators are in parallel. Try this - Pop the connectors off on all four doors. Now, only the gas cap actuator is in the circuit. Does the central locking work (gas cap only, 'natch). If so, add back door lock actuators one at a time. If one causes it to stop working, leave it off and connect others.
If just one actuator is causing the system not to work, the actuator may be pulling too much current, and replacing it would be the best choice. The good news is that all door lock actuators are the same across the 9000 years. The brackets are different in different locations, but you can swap the actuator out. So a junkyard would be a good choice.
If it doesn't matter which actuator it is, but say it works with any four (3 doors and the gas cap) but not with five, then the problem would likely be the ground to the box, or the relay inside the box. I'd trace the large black wire from the box's pin 3 to ground, and clean up that ground. If that doesn't do it, I'd look for a spare box. (Actually, I'd open the box and clean the relay contacts, but that's me.)
