Would the motor being bad explain the lack of voltage at the switch though ? Like it’s shorting in the motor or something ? It is very old fixture.

I have limited experience, but depending on the fixture there can be (note can be) a smaller fuse inside the motor that could interrupt the flow. Might find a part number and see if there's a manual running around the internet.

Are you sure you've got the voltmeter set on AC and not DC?

If it is set on AC, I agree with other posts about something upstream like a tripped breaker. There should be 120V at the switch.

I ask because I often go between testing AC and DC and sometimes forget that I have it set to DC when testing and AC circuit, and vice versa. That low 0.3V is often what reminds me to change it.
