Help! Rear passenger window disapear

[GT475]

Good morning all,

We own a 2001 3.0 man trans for well... 7+ years now (Oct 2000).

Yesterday, on her way home, my wife hears a big noise from the rear passenger side: The window disappeared.

She tried to lift the window using the control but no go.

Once home, we looked through the door opening and sure enough the window glass is in the door like if it had came off the lifting mechanism.

We have an appointment to the dealer for Tuesday but I would like to remove the rear door panel trim and see if I could temporairly fix it until Tuesday.

Does anybody can guide me to the sequence of removing the passenger rear door panel trim?

Thanks

Marc
