2002 Yukon XL Interior Lights Problem

A few days ago my wife activated the passenger side light (push button) and when she started to move it to the desired postion it went out. Now none of the interior lights come on and the sunroof will not work. I have already checked all fuses pertaining to the interior lights or the sunroof.

So I tohught it was a bulb, dealer says the entire unit must be purchased as there is no bulb replacement and it's $800.00.


Help!!!
