When I turn my dimmer dial all the way up none of the interior lights come on, when I turn it to the 1st dial spot none of the lights come on also. Shouldn't some or all of the four rear lights come on with one of the dial postions?

All the way up should turn on all the dome lights except the front "map/reading" lights.

The first position up will increase the brightness of the odometer, radio and overhead displays when the park lights or headlights are on.

Do the lights come on when you open the door?

the only lights that come on are the front two reading lamps, and the rear liftgate light.
