93 Blazer dome lights won't go off

8 lights total, all on with all doors closed. All door switches ohm ok and work. Dash rheostat switch can be off or disconnected. Other items on same fuse work fine. Driver's door switch has two wires, other three have single wire. Is there a relay? Can't find one. Drivin me nuts. Gary

There's no relay, but check the switch for the rear hatch and also the rear dome light if it has a switch. Rather than check the switches, disconnect them. That way, you totally eliminate the switch. I assume that you don't have any accessories that tie into the lights, such as an alarm. Otherwise you have a short in the white wire from the switches to the lights.

One of the door switches is not working properly and is sticking.

I disconnected all four door switches and the cannon plug from the int. dome/dash light dimmer and all lights are still on. You can't even turn off the rear view mirror or overhead console lights with their buttons. I will check the hatch and rear cargo
