Reverse lights not working - Think its the switch but where is it?
 

I have a 2000 Passat V6 automatic. The reverse lights don't come on. The light bulbs and fuse are ok, so I think it must be the switch that is gone. I have seen some videos online about where to find the switch on the manual transmissions, and how to access it for a 4 cyl. But, I have not seen any way of locating the switch on an automatic or how to access with my V6.
Any help would be appreciated.
