I've been reading for hours. Finally decided to ask. I have a new-to-me XJ (99 Sport) and when I turn the headlights on, only the driver's side is lit, front to back. The passenger side headlight, parking, side marker and tail lights are all out. However! The headlight comes on when I engage the high beams. Turn signal "works" but at 3x the normal speed. The brake light works and reverse lights work. This led me to believe it was the headlamp switch in the dash. I changed it out and it did not fix the issue. I changed the headlight and parking in the front and of course didn't see a change there either. I don't have a diagram and not sure I could read it well enough regardless. I'm looking for any advice I can get. Thanks in advance.
