Electric rear windows will not open!

[JIMAFC85]

Hi, i have a problem with electric rear windows on my 156... when i press the button to open them i can hear the motors working but nothing is happening. i thought that maybe they may have come away from the motors however it is strange that both have stopped working at the same time... I have a lock facility on the drivers door controls...might this be causing the problem?

any suggestions/input much appreciated!

same thing happened to mine about 1 week after I bought it, both at the same time...

I too have a mysterious LOCK button that seems to do... nothing?

The "lock" button stops them being operated from the rear seats

It is well worth operating the rear window frequently, as lack of use leads to malfunction. Very fiddly to replace and many variants available, be careful. Get the old one out before buying a replacement, can be expensive !!

If you can hear the motors running, then you've probably suffered the common snapped cable.......as curlygrey says, if not used regularly they seem to jam in the runners, and water that gets inside the doors seems to rot the exposed portion of the cable, which then snaps.

Replacement isn't difficult, but does take a bit of time....and getting the watershield off the door without ripping it is VERY testing

I wouldn't say there were "many variants" - I've sold loads and although there are variations in the type of clip that fastens the mechanism to the glass, they are interchangeable. Saloon and Sportwagon are listed as different part numbers, but anecdotal evidence says you can use a saloon one in a Wagon.....
