The standard test is to short one of the door switches to earth but if that doesn't work, you'll have to sort out the black box which you won't be able to hear switching off because it is electronic and contains no relay.
I suspect it may be hidden under the centre console but it may be behind the dash!
The wiring goes into the box on a seven way connector. Pin 1 is unpopulated. Pin2 is the "off" trigger from the ignition switch. It goes to 12V and the lights go off.
Pin3 is the "off" trigger from the central locking. Lock car and the lights go off.
Pin4 is the "on" trigger from the four door switches. Ground any one and lights come on until door shuts and the delay elapses (unless door button pushed down or key turned).
Pin5 Output to lights. Pulls them to earth which is Pin6. Pin7 is the permanent live (12V).
If it fails to switch the liglts on, check 6 to bodyshell, should be short. 7 to battery+, ditto.
5 to open side of light switches on pillar. Ditto.
Interior light delay debugging.

Right then Tim, time to check the wiring in the light unit. try swopping the two wires on the bottom of the unit over, that may cure the light problem on the drivers side when the doors open.
As for the "door open warning" display, they are triggered by seperate switches that are in the lock mechanism itself, not the switch on the "A" pillar. Suspect broken wires between the door and "A" pillar...
Cheers

Oh ah, hadn't thought of that!
Although if only one is working, and I know it sounds daft, but if you swop the two connectors on the bottom of the light unit it should cure it. Did on mine anyway! One connector has one wire and the other has two....
I'm no electrician by any stretch of the imagination but thats what I did on my valver and hey presto! Both lights working as some sweaty french bloke intended!
