the other daywhile driving i accidently hit the sunroof while it was in the closed position. now the headliner on the drivers side (i hit) doeshnt open but the roof opens fine in ventalation mode. however thats all it does. It doesnt open in the full mode at all. This roof looks pretty complex. How do i remove the headliner and or sunroof to fix or replace whats roken. there are several w124s at the wreckers so getting parts should be ok. Any diagrams or things to watch out for?
