Grateful for any help with the following as this is really puzzling me and has just failed its MOT because of the rear lights.
With the ignition off and the parking lights switched on (middle position on light switch) only the front lights work, the rear lights don't. The rear lights themselves are OK as switching the ignition on causes the rear lights to light correctly.
Have checked all fuses, swapped the light switch unit but still not working. Managed to identify the blue/yellow wire from the light switch unit which using a multimeter is working correctly however I cannot trace where this wire goes to on the fusebox. The Haynes manual says the wire goes to C2 which should then connect to G10 which is a grey wire to the rear lights. Does anyone know if the connectors are marked as G or C ?
Grateful for any responses.
Alan
