You could also just push each door switch in and out a few times. Might fix itIf dome light is on, but dim, one of two door switches has a high resitance, as in not opening all the way. If you unscrew the body of the door switch from the body, one door at a time, I suspect you will find the faulty door switch. Unscrewing the switch body from the body opens the circuit, light should be off.
Orange wire is power to d/light, white wire is ground when switch is closed, aka, door open.
