98 Sport headlight problem

[RayRay65]

I have a weird problem with my headlights. I replaced the housings and bulbs the other day. The only headlight that was working was the low beam on the right side, neither working on high beams. I put the old bulbs back in, same thing. First thought was the multifunction switch. Put in a new one and nothing changed. So, before I go and get any more parts, I thought that maybe someone here might know what my problem is. Also, the high beam indicator on the cluster doesn't come on either. Thanks in advance!

fuses?

Relay, headlight switch, bad/corroded ground wires?

There are fuses and relays for the low beams and high beams

Check those first

This website startmycar.com has excellent fuse box diagrams

Considering the age of the vehicle, I would have concerns that disturbing the wires after all these years, they might be damaged from an insulation failure causing a short, or breaks in the conductivity of the wires.

I have attached a wiring diagram for the headlight circuit. Without trying to guess too much, having the right low beam working is a good start, then you know that it has a working ground, so what I would do is trace the right high beam circuit path with a multimeter to see where power stops. It's highly likely to be a problem before connection S111 in the diagram since there was no potential trauma to the dash wiring and the high beam light on the dash isn't coming on, which would still if there were any fault after S111, between it and the bulb.

If all else fails, while doing the multimeter probing, you could find the last point where there is power and make a new wire run to the bulb connector from there.
