Try resetting the windows
Switch on the ignition.
Press and hold the relevant switch until the window is closed.
Release the switch.
Press the switch again and hold it (closed) for approx. 3 seconds
Turn off the ignition.
Thank you for your method. At the moment it looks as though your remedy really works. The cars annual service and MOT is booked for later in the week. Having fixed the window problem, will lessen the bill.
