Dome light not working when door is open, but works when pushed

The left dome light doesn’t come on when the door’s open or on the “On” setting but the right one does both.
It comes on when I press it so it’s getting some kind of power and the bulb’s not burnt out. I tried replacing the bulb just to be sure and same thing with the brand new one.
The overhead switch is set to door; I’ve tried going back and forth between all the settings and still nothing.
I don’t believe it’s the door jamb switch either. When I press it, the door and trunk lights come on.

At this point, I’m assuming a blown fuse or short circuit somewhere. I even checked the fuse box under the driver side dashboard but I’m not good with electrical so I wasn’t sure what to be looking for.

HELP! I’ve done all the trouble shooting I know how to do and am at my wits end.
