headlights won't turn on.
 

I have modded my headlights months ago, out of nowhere the low beams have stopped working, all of the other lights are fine. I have tried swapping in new bulbs that didn't do it I swapped out the fuses in the ipdm that didn't do it what else could it be? Originally it was only my driver side and as I was trouble shooting it I plugged the passenger side headlight into the driver side harness and now the passenger side doesn't work. Also I did notice that recently a lot of condensation got into the driver headlight could that have anything to do with it?

Bad ignitors, ballasts?

I originally thought ballast but wen I switched ballasts from the working side (passenger) to the none working side (driver) I got nothing. Then I switched them back and the passenger side was working again. Then I unplugged the whole passenger head ight and plugged it into the driver side harness and now neither side works. I feel as though it's something with the harness that's causing my issue?
