What do you mean exactly with the 'units' are fine? Do you mean the panels with the lights on, or the electrical modules behind the dash? There are 2 modules, one does the warning lights for the head and tail lights and the other module controls the door ajar lights, low fuel and washer level and the outside temperature warning lights. Both these modules are powered from fuse 22 and have the earth on the steering column bracket.

I would first check fuse 22.

Then start with checking both modules . If these are OK I would check if 12V comes to the modules (pin 2 on the lamp module and pin 17 on the door ajar module). Also check if the earth on the modules is OK (pin 6 on the lamp module and pin 16 on the door ajar module).
