I’ve done a search and can’t find the answer to this question.
I have a 2014 Calais V with front and rear roof reading lamps (old school incandescent bulbs, T10 / W5W wedge).
I replaced both front and rear dome lamps and they work fine. But when I replace the four reading lamps, only the drivers side (RHF and RHR) lamps will work. Passenger side lamps don’t work, or stay on (won’t turn off with button). I’ve tried different bulbs including ones I know work, so it’s not dodgy bulbs or wrong polarity. I’ve tried three different styles/brands of LED’s but they all do the same thing.
I’ve pulled out both front and rear lamp assemblies and tested them for shorts but can’t find anything wrong. When I put the old incandescent bulbs back in they work perfectly so it’s not the wiring either inside or outside of the units.
Are there special bulbs I need to use?
