Check out the door light on/off switch for each door.

If a switch has failed in the shorted mode--the interior light/door chime will be constantly activated unless you have them off at the dash.

Does your vehilce have the message system that reports door ajar? If yes--does it show a door ajar?

Tail gate switch--same questions.

If one of the switches has been pushed out of the door jam and fallen into the body cavity you will have the same ligh/chime issue.

The fan and light issue is a new one for me.

Have any electrical mods/repairs been made/attempted just prior to this issue arising?
