On my 87 Wolfsburg, all the interior lights can be turned on and off with
the two front doors when the individual switches are set to 'door.' But they
do not work with the rear sliding door. I cleaned out the contact point at
the sliding door switch on the pillar but it still doesn't work. Also, I
confirmed that there is no voltage at the wire in the sliding door switch on
the pillar.

Also, the flourescent light works only when a front door is ajar. I cannot
turn it on with all the doors closed. I think these two problems are
related. Can anyone help me with this?
