Hey Utah,
To get it to stay open, right when you kill the ignition it will beep once and start closing. If you press the open button once it will remain open.
When they moved the dome light on mine it now takes more force to get it to work by pressing it - it still works fine when the doors are opened for me. Since I rarely press it for light it hasn't bugged my too much. I don't believe it's a wiring thing, but rather a product of where it now mounts.
-- Best, John
