Window on WDB 220 Strange Power Window
 

My Window Rear Left Just went down while driving without touching any buttons on it..

and sometimes the central locking system does not function at all

the stranges part is the rear trunk just automatically opens it self ..

any advice?

Sounds like a problem with the master window control switch in the driver's door. It also contains the trunk release switch. The control assembly could be dirty or corroded due to water dripping on it. Another thing is that when the door is open and shut numerous times the wires in the loom at the hinge can break especially in cold climates. This will lead to problems with wires broken and grounding against metal. Maybe you could try removing the master window control assembly and cleaning it with an electronic type cleaner spray.
