i have a 04 s60r with 160000 miles. about 2 weeks ago the pass headlight blew and i ordered new bulbs. after the bulb blew the msg board said bulb failure low beam. today i got my new bulbs in the mail and when i put them in it didnt work. so i checked the fuse box. fuse was blown so i replaced it. still didnt fix it. i switched the ballast with the other headlight and it worked. i tested the plug and there seems to be current there so i have no clue whats going on. any help would be appreciated
