Two things malfunctioned with my Skoda Octavia windows
One window won't operate with the 'one-touch' switch, only by holding the switch
The 'convenience' window operation from the key fob stopped working
I tried the following
Using the other key fob
Replacing the key fob battery
Resetting the window options to 'factory settings' and set it up again
Replacing the four-window switch unit in the driver's door
but nothing worked.
