Fog Light Switch Problems of Dodge Ram 2500

Hazzard: intermittent head lamp operation (low and/or high beam cut-off) cause: unknown. Safety issue: keeping the headlamps on while driving (Dodge ram 1998. 5 2500 4x4 quad cab slt; 5. 9l 24v cummins diesel; 47re; stock (no fog lights); 170,000 miles). Problem: headlamps (low and/or high beam), and occasionally, but not consistently the dashboard lights, cut-off intermittently -- actuating the dashboard mounted headlamp switch (push-pull) restores the lights. Trouble shooting/repairs (executed by a certified automotive repair facility): (1) checked multiple grounds (clean and tight); (2) checked fuses; (3) checked output from generator (steady - approx. 14. 5 with "no load"; batteries - new 6/18); (4) checked circuits (verified continuity and resistance); (5) replaced steering column mounted multifunction switch; (6) replaced "headlamp/security" relay; (7) replaced headlamp/dashboard lighting combination switch (replaced 22 months ago (167,000) - original failed. Note: dashboard above switch - warm to touch. (8) replaced headlamp bulbs (both). Note: no diagnostic trouble codes set. Next action: replacing the headlamp/dashboard combination switch again. Oem replacement switch installed at approximately 167,000 miles may be malfunctioning. A visual inspection of the switch did not indicate signs of overheating. Actuating the switch indicates normal operation. Speculation: a "ccd bus communication error" is occurring; pulse from pcm (?) to headlamp circuit may not yield the level of resistance required resulting in the intermittent "cut-off". Technical advice/guidance/assistance either directly from the manufacturer (fiat Chrysler automotive), or through the Dodge ram dealership network is required to correct this hazardous condition.
