So the other day I was changing out one of my lowbeam halogen H7 headlight bulbs that had burned out like I've done a million times before no problem and when I went to turn on power to check it I all of a sudden had no headlights. My highbeams work fine and corner signal lights work fine, just the lowbeams not working. I checked all the fuses and everything looks good which makes me believe it's a short or something in the wiring. Im not very good wi th electrical and don't know where to start or where to look. Anyone have any ideas for what wires I can look at to test I would greatly appreciate it.

I would first check the H7 socket that plugs into the bulb... After heat and time, it can become brittle and thus cause a bad connection... I had that happen on my '01 S40 I used to have, and I replaced them with heavy duty ceramic sockets. Also check the connections of the power harness that plugs into the headlight housings which provides the power for the high/low beams as well as the turn signals. Just for kicks, try replacing the low beam fuse if you have any of that rating on hand. Good luck!!

Thanks I'll look at that stuff and let you know what I find. I know that I'll probably need new bulb connectors for the H7 bulbs, found that they are cracked and falling apart but wires still are in tact.

Super easy fix!! It's the socket that the bulbs plug into. I had the same issue. Bought some generic sockets at AutoZone for a few measly dollars. Cut the wires, removed the old sockets, spliced the new ones on, and haven't had a bulb go out in two years.
