When battery is reconnected, the window should drop right to the bottom. To calibrate it, the ignition is then put on and the internal switch used to put the window back up again.

Did you change the motor with the window mechanism? Inside the motor is a hall effect sensor which tells the CCU how much it has moved. These can fail and so the CCU is still confused. If there's nothing physical obstructing the window dropping fully then I would be looking to substitute the motor. Also check the wiring and connector through the door hinge as they can break.

Nodge; the window doesnt drop,
andy. no i havent change the motor, the wiring must be ok because the window goes up and down all the way with switch- key- or doorhandle, only by 2cm each time, ok for the sensor story, ill try to find an other motor, thanks

Your problem is that the window doesn't drop when battery is reconnected so the CCU has no idea where the window is and therefore does not allow wiper to work.
If the wiper motor hall effect sensor is not working then the CCU will not get the correct signal and may not drop the window.
As Nodge says it is unlikely, but possible! that it is the CCU. Much easier to change motor first.

You're welcome, but full disclosure, I didn't invent the mod. I believe it came from the Rover forum, where owners of the Rover 75 (same engine) had the same thermostat issues, and it's just as long a job to fix, so someone came up with the in line mod.

Great news. Must have been the hall effect sensor then. This can be replaced with a £3 item if you don't mind soldering. I posted how to do it a long time ago.
