working on a few bugs on this 74 dart sport I just got. The dome light works if u turn the headlight switch all the way to left. Otherwise when u just open the door u get the buzzer and the light doesn't come on. All fuses are good and I tried plugging the seatbelt system back in and it didn't help. If it makes a difference the radio doesn't work either, along with the light for gear indicator. Thanks for any help.

Welcome aboard! I'm in Maryland, towards Churchville area.
The dome lamp always has power. The door switches and turning the headlight switch provide a ground path. The seatbelts are a separate circuit, not related to the dome lamp. Some door switches have two ground wires, both likely yellow. The left switch may have three on a plug. Make sure they are providing a good ground.
