Your Caravan has what’s called an Integrated Power Module.

This module controls all the functions of the exterior lighting.

Looking at the wiring diagram, this would the be first component I would suspect to be causing the problem.

Those lights are also controlled thru the Integrated Power Module.

The multifunction switch is common to both problems.

It’s on the steering column.

If the lights you are talking about do work when the head lights are not on then I suggest you check the ground to those lights for a bad connection.
