Front interior light - Partial Illumination

[jwykes]

I need some advice on an issue I have with the front interior light in the headliner

When I open a door only 2 of the 3 bulbs illuminate. The one that does not work when the door opens, works if you press the button.

Any ideas where I can start to investigate?

Yes, remove the bulb and refit it, itll be a dodgy connection, if that doesnt work remove the interior light and clean the contacts in the switch.

Swapped the bulbs and bulb holders over, no change. Then pushed the exposed metal electrical tracks on the offending lamp, and bingo. Must have been a small amount of corrosion. All fixed and back to 3 lights
