Headlights only one working

1994 Volvo 940 one headlight is working. New bulb in other one not working. If I put the brights on they both work. Have voltage at the plug, voltage at the relay.
Is it the relay itself? Is there another in the cluster I can swap to check?

OK something new. If anyone can help I’d appreciate it. As per my previous post I thought when I put the brights on that both of them were working. As of right now my passenger side headlight only works but my driver side does not. When I put the brights on the driver side bulb lights up but I have nothing on the passenger side. This makes no sense and I change the relay

Check the condition of the wires near the headlights. The insulation may be failing and giving strange results. This may also cause various, changing faults.

Ok so the voltage I get on the side that works is 10v on one pin and 12 v on the other pin.
The side that’s not working is only showing 10v on each pin. Ugh wiring looks good
