Glove box light was working fine initially. Removed glove box and light and put in LED. Wouldn't work either direction. Swapped LED and same issue. Tried original bulb and now doesn't work at all.

Interior lights all working fine. What's went wrong?

The switch on the glove box light usually breaks, count yourself lucky it's broken in the off position otherwise you'd have a flat battery by now.

The switch has a self destruct mechanism. As soon as you look at it, it explodes into pieces.

You're right. Bulbs checking out fine and so is the wiring. Looking at the switch & bulb holder just now and it's hard to see anything wrong with it but will try and work it out. Anyone else had a problem with the switch and got it sorted?
