Trunk light

[Space]

My trunk light doesn't work. There's no voltage from the wiring. Does anyone know what triggers this light? Is there a switch somewhere?

There's a microswitch in the boot lock mechanism. These often fail and are about a tenner to replace from the dealer

Is this switch located in the rear door where also the wiper mechanism is or is it below behind the bumper?

[alexperkins]

In the door itself.

Lock is removed from the bottom with an M8 spline bit

The switch was very polluted inside and sliding contacts corroded. It was easy to replace and a good moment to lubricate the locking mechanism as well.
