I just had to replace the passenger side front fog lamp housing in my 2002 4matic wagon. Ever since then the drivers side fog lamp has been working off and on. I feel like this wouldn't be because the bulbs burned out since it does occasionally work. So I was wondering what would cause this and how I should go about fixing it. I will note that the new passenger fog lamp is an eagle eye and not a hella brand due to a mix up if that has anything to do with it.

from memory, the lights are on separate fuses, though they share the same
switch. both should be H3 bulbs. i don't think the flickering would be caused
by your new pax side addition. so check for loose connection or bad ground
in the driver side lamp, spade connections, sub-harness
