2016 Chevrolet Crew Cab LT has the following problem. DIC says rear driver's door is ajar, dome light stays on unless the dome switch is used, power window will not work both in the door itself and the master switch. Power lock works. Door was looked at by body shop, no issues in lining up. Power is going to the switch in the rear passenger door. Is it just the switch that has to be replaced? Any ideas?
