So I was changing the low beam bulbs and now the low beam bulb or DRL does not function. Only the high beam bulbs come on. I even bought a new harness with the sockets and that did not fix it. The old socket was brittle and fell apart.

Dumb question, but is there any reprogramming when changing the headlamp bulbs?

I have a 1998 V70 wagon with the H7 bulbs

 

Gonna check fuses...hope its that and not something major...electrical is not my favorite.

 

I started this thread gave advice on this thread to check the fuses and solved the problem lol. Popped that fuse cover and yessir the fuses were blown. Not a real mechanic, but had some sense to remember checking the fuses. I put the new harnesses in and got rid of the old crusty and brittle harness.
