low beam and high beam not working correctly

I have a 98 Passat. 277k.
Recently I replaced the factory headlights and corner lights with a set of aftermarket OEM style housings. they are not great, but are super clear compared to the clouded original ones (I kept the originals and may try to clean them off the car). The issue is that a few nights ago, I started noticing that the lights were not looking right. I determined that the low beams are on they are fine. But when I turn on the fog lights, the driver side low beam shuts off. At first it would come back on after a couple of seconds, but now it does not. When I turn on the high beams, the low and high beams do not work on the driver side. Help?

A sidebar to this is that I was pulled over one night for no tail lights. Once I got home I found out how to pull the main switch. I did this and unhooked it from the harness. I plugged it back in and for fun checked the tail lights. They were working.....

I apologize if there is a thread on this already, but I cannot find one so far and need to drive the car in the dark tomorrow and am concerned about the lights....

I will try plugging in the old light. If it is the fixture, what am I looking for to repair?

Is the main light switch a switch I can take apart and clean? I did that with the window switches in my 1987 Supra with great success....

I forgot to mention, the day-time running lights have not worked for several years. Is that also switch related?
let me note that my headlight switch is on the dash, not the stalk on the column. Also, the replacement headlights were OEM so I did not alter the wiring in any way to install them.

Does this info change anything stated above?
Where is the grounding screw?
