i have a 2001 durango V8 (not the 5.9L)...my tail lights do not work. i have checked the fuses and bulbs and they are intact. not sure if this is related but have no console lighting either. how can i check a relay or switch?

 

Check the brake switch directly above the brake pedal.

Also check relay #1 and #6 in the PDC under the hood.
As for the interior lights, check relay #7. Also do the interior lights just not work completely, or just certain times (ie. when you open a door or slide the dimmer)?
