Vanity lights and rear passenger lights not working

[casharp1]

Hey crew need a little help, I have a 06 base model Cayenne. Bought it several years ago and at the time I did not notice that the vanity mirrors light and the rear passenger lights did not work. This was not a problem until the wife made it an issue. Now I have to fix it! About a year ago I did take it to Suncoast to have it looked at but some how they broke the my passenger seat back off and then blamed us for it becuse I was have $500.00 oil change done while driving a broken ghetto machine. Well needless to say it was the first and last time I am going there($750.00 for one seat back installed). at the time all they could tell me about the lights was that it is a bigger problem, but I was so red in the face I told them not to touch the car any longer.

Things I have done

1. Checked the fuses - all good

2. popped out a light and put a meter on it and no voltage.

any ideas would be very helpful
