try replacing the master switch it maybe malfunctioning due to wear.or may have shorted out by getting wet or something.since it is the primary control for all windows and power door locks.

You can try a different switch. If both switches have same effect, then the motor is wearing out and will need to be replaced. The door panel will have to be removed to access the motor

Electric window motor seized. Those motors have internal copper brushes that usually lock after time. Some times a quik test is to get to the motor and tap it with a wrench while pressing the switch to get it unseized. ( Not a fix ! ... still needs replaced ).

check the parcel shelf has been refitted correctly as there is a micro switch on the left hand side that stops the second stage of the roof from opening
