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

May have been covered already but ..

The switch side of the dome light cir is a switch to ground. That means a ground ANYWHERE on that wire will cause the dome light cir to stay on.

Assuming you have had BOTH door switches AND the headlight switch disconnected at the same time AND the light still lights that would indicate a shorted wire somewhere.

Finding the shorted wire will be the hard part.
