Ive just noticed that despite my interior lights working fine on the door switches you cant turn them on on the actual units, anyone know why that could be?

When I play around with the interior lights I first take out fuse 17, as it blows easily. Then lift out the lamps. Then put the fuse back in. (You will have to reprogramme the radio stations after as it works on same fuse.)
Check, with a test light (make one with a bulb and two wires if you don't have one) next check that you have positive feeds. Dodgy contacts sound the most likely but strange you have that on both lamps.
I'm racking my brain to remember what the wires should be. I think it's one live, one earth and a switchable earth (the door switch).
It could be you have a bad common earth on the permenant earth where both wires meet and join the bodywork.
I'm just making assumptions here and have no experience of this exact problem.
wiledw - if you take out the door switches and pull them out carefully with wires still connected (don't disconnect them) and clean up the contact area - i used a cloth for grease and a small file to be sure the contact was fresh.

if you remove the light unit and watch it from the back when you switch it over youll probly find the little copper bar isn`t making a connection(for light manualy on) it`ll just need bending over slightly.

Who needs lights, just the gentle touch is all thats required.

This is probable, but if someone has been messing with the wiring in the past, it's possible to put the connectors wrongly on the interior lights to give the problem you describe.drewjak wrote:if you remove the light unit and watch it from the back when you switch it over youll probly find the little copper bar isn`t making a connection(for light manualy on) it`ll just need bending over slightly.
Not working on the doors is the door switches themselves.
Take them out - don't let the connector slip back through the hole!, and clean and lubricate them (silicon grease). Also trim away a sliver of black plastic that builds up at the contact point.
