1978 Buick Electra 225

On all older GM vehicles the door trigger is white (negative). Get this at the door switch, jam/kick area OR at ANY domelight. Now this car is old as Moses so some of the door switches may be bad, you need to make sure each door turns on the domelight. Check all fuses as well since on the older GMs many circuits share the same fuse and dimes end up falling in the cig lighter socket etc., see it happen.
