All.
1991 4x4 2500. Got home from camping and the next evening noticed the 2 dome lights were still on inside the truck. I don't have a service manual or wiring diagram.All 5 door switchs were checked with a multimeter and look ok.
I have not taken the light switch off the dash yet.
Any other quick suggestions of where I may look
Thanks in Advance.
P.S. The battery has been charged and the 2 lights removed.
