Hope you good people can help...

Recently I shut the rear door to hear a tinkling sound which sounded like something coming loose and finding its way down the inside of the door. Then I noticed that rear window wouldnt work.
Shortly afterwards the same thing happened when closing the opposite rear door and that window stopped working too. Tonight my passenger shut their door only to hear a tinkling sound again...yep, I now only have the driver's side operating. None of the malfunctioning windows work from either the drivers panel or their own switch.

I know about the reset procedure and have used this when the battery has gone flat - this does not work here.

The window lock button has no effect.

The tinkling sound obviously means something has come apart internally and this will mean taking the panels off each door...before I did this have any of you folks experienced similar and could helpfully point me in the right direction?

Thanks in advance,

Gowza
