I have the 2001 is 300, and I recently have been having headlight issues. Bought bulbs and replaced both low beam headlights and the right side works fine now but the left side won't turn on at all. Checked the left headlight fuse (10A) and it was blown, replaced it and when I tried to turn them back on it blew, again. Went through like three 10A fuses and can't figure out why it keeps blowing. Anyone had this issue?
