JT406

So I have a 2000 Subaru Legacy GT Sedan that I’ve had about 2 years and just over a year ago the windshield wipers and sprayers started going off non stop. Pulled the fuse to make it stop and just used a bunch of rain x to put a bandaid on it. Just last night I was on my way home and my passenger headlight went out shortly followed by my drivers side headlight. When it went out I heard a loud click. The brights still work but no DRL or low beams. Both fuses are mint as is the relay and the bulbs, any thoughts on what this could be? Also upon looking it seems that there was a blowout on the drivers front tire that really messed up the wire harness, does anyone think this is the culprit and if so what portion of the wire harness is this?
