Found the Problem
After much chasing wires and checking various modules, I isolated the problem to the "black box" that moniters the light system. The one that reports to the system status display on the console if a bulb is burned out. I installed a jumper to bypass the "black box" (located behind the left headlight) and now the right low beam and the fog lights work just fine. The only problem is that the console display tells me to check my headlights every time I turn them on. I press the reset button to clear the message and all is fine till I turn the lights on again. I'm checking on the cost of a new "black box".... I may just live with the nuisance. Thanks to those that offered advice.
