hi guys,

its not a veccy, but my bother-in-law is having trouble with his rear doors on his zafira 2.0 dti. the passenger side rear door doesn't open at all. but also the door speaker and electric window have packed up, theres no lights on the switchs either. front or back.
also in the last week the drivers side rear door is now playing up the speaker and window have stopped working, but the died lock still works so the door is still opening, for the time being!

is there a main control unit that may have failed? or maybe an earth problem. but not sure that would effect the speakers.

there are multi plugs in the doors which all look good, no corronsion or damage.

and front doors are all working fine.

does anyone have any ideas.
