First place I would look at is the switch in your car that operates the roof. If it were me I would disconnect this switch (requires removing the panel in which the switch is fixed) and seeing if the problem goes away.

If it doesn't then, it may be the switch connected to your door key-lock

Mine's a coupe, but I can close my roof and windows by holding the key in the door. I think you can operate your roof and windows by doing the same.

That means removing the door panel and disconnecting that switch.

Either way you are removing panels.

Where is the roof switch on the inside of your car located? If it's on the horseshoe surrounding your radio then it's easy. If it's in the console by your shifter it's a bit more work.The door panel will be hardest I would think...I haven't had to do that one yet myself.
