Hello, I have a small problem with the interior lighting on my Vivaro Life. The front lighting turns on/off when the driver or passenger door is opened/closed. The rear lighting with additional reading lamps above the second and third row of seats cannot be switched ON/OFF via the front or rear doors. Manually, however, this works. Each of the rear lamps has a toggle switch with three positions. Switch positions for MANUAL ON, OFF, and TURCONTACT CALLS stand. However, this is not the case. I cannot set the switches so that the rear interior lighting is switched on e.g. with the sliding door. However, the door contact switches seem to be OK, since the front lighting works. Can someone give me a hint, what am I doing wrong? The operating instructions do not give anything usable. Mfg. Tom
