Another Dome Light Issue
A friend has an '00 F250 Ext. cab. Cab light and "door Ajar" light comes on when hauling a heavy load (20,000 lbs). Usually comes on when you are coming to a stop, then goes out when you get over 25 mph.
Every now and then, the cab light will stay on over night, killing the battery.
I have checked the switches and fuzes. Is the load tweaking the truck enough to turn on the light? Is there an adjustment to the door switch?
Where to continue looking? Thanks for your help.
