Headlights do not illuminate.

When headlamp switch knob is pulled out, headlights do not illuminate. Parking lights come on, rotate knob and dash lights dim correctly.
Insert key into ignition, turn to on/start, move multifunction switch on left hand side of the steering column upward or downward position turn signals flash correctly. Push multifunction switch towards dash for high beam or pull back for low beam and no high/low beams, do not illuminate.

Checked fuses at right cowl side inner trim panel inside vehicle, all good.
Checked fuses in Power Distribution Center under hood located on passenger side wheel well of engine compartment all good. Note in both fuse locations, fuses pertaining to headlamps were removed and checked for continuity, all good.

Replaced right and left front headlamps, Note used electronic cleaner on connection, checked for broken wires, all okay, and applied dielectric grease before connecting to headlamp. Pulled out knob, headlamps do not illuminate.

Replaced headlamp switch, old switch did not show signs of burned areas or broken wires, pulled out knob, headlamps do not illuminate.

The vehicle is equipped with a device which shuts off the headlamps automatically after ignition switch has been turned off.
Is it possible the automatic headlamp shut off may be the reason why the headlamps do not illuminate?
If so, where is the device located?

Or could it be the multifunction switch on left hand side of the steering column.

The vehicle has not been in an accident and is garaged nightly.
