2002 Durango question

Well, it IS a Dodge :) Picked up an 02 Durango SLT for dirt cheap to use as a tow vehicle a few times a year and as a backup vehicle if the DD needs work. Going thru everything today, put the trailer on it for the 1st time to check lights etc. and noticed no running lights lit on trailer, they worked fine last week when it was hauled to the house.

Started walking thru everything, got a friend over to check trailer plug etc while turning lights on etc. and noticed I suddenly have no headlights :shock:

Tail lights good, brake lights, turn signals, running lights, fog lights, power locks, remote unlock/lock all work. Googled and keep seeing the CTM being mentioned but usually there are all kinds of other goofy things going on like intermittent dash warning lights, flickering dome light. Anything I should look into before I drag the damn thing to the dealer ? I know the CTM controls all of that other stuff.

Thanks!
