My 02 Durango SLT has recently been having an issue where while driving the headlights and dash lights will get dim and bright and just flicker back and forth not sure what the issue is I've already replaced the alternator 2 days ago and didnt fix it fuses and box fuses are all good, any ideas?

 

Headlight switch or cluster connections.

 

Where is the cluster location i know my dash cluster but where's the connection cluster

 

Connections to the cluster are behind the cluster.

 

Not sure if the newer Durango's are the same as mine but I had a very similar issue on my 99 5.2 SLT 4x4 where the headlights would flicker on and off only on the low beams though. It ended up being a wire on the bottom side of the steering column that had tension on it from the tilt wheel going up and down... it was literally pulling the wire out of the plastic pigtail end and intermittently making connection.. it was one of the wires in the pigtail that is held on with like the 2 inch long 8mm bolt I believe... remove the tilt wheel lever. pull the plastic case off of your steering column, I believe another smaller plastic case has to come off underneath that one if I remember right, then, take a small pair of needle-nose pliers and start jiggling one wire at a time.... I jammed a piece of Toothpick inside the plastic mold to hold the wire in place and it worked great.
