I have no tail lights on my 2007 Chevy Express Van

Thank you very much for your help. Unfortunately one connection connects all of the rear lights, brakes, blinkers, and tail lights. Brakes and blinkers work, but not the tail lights.

I wanted you to know that the problem was found and solved. Something (we don't know what) was disconnected from wires under the front seat. The wires were left uncovered and connected with other metal, shorting out a major fuse we had not found. All is now fixed and we have tail lights! Thanks for your help.
