hi guys, i need some ideads for a small (i hope) electrical issue. my 69 barracuda notchback interior dome wont shut off.

Well you gotta chk the entire length of wire for that circuit. Car is 55+ years old, who knows what's been done to it.
sill plates r off for other wire runs. will check there for shorts. the overhead dome light plugs into the harness in the trunk that runs through the sill plate on the drivers side. it feeds down from the roof panel down in back of the rear window into that sill panel
