Im thinking this is one of the switches? Both the door light and window stopped working at the same time, maybe its a coincidence but im guessing related.

Anyone know what could cause this?

 

I'll guess you are talking about the light in the door that comes on when you open it?

Best to pull the door panel and do some testing.....is the bulb good? Are you getting power to the light....when the door is open are you getting ground to the light.

Almost the same with the window motor....

 

It is possibly due to a broken ground wire or wires at the passenger door jamb.
