Hi
You might be suffering from the common 'faulty window switch' (they are a bit feeble - to say the least - and prone to contacts/switch degrading).
Do you hear a sharp 'click' when you press/raise the switch? If not the switch may be worn.
Try spraying some wd40 over the drivers switch (try to make it go through the lower part) then put your finger under the switch to fully support the switch when you raise window.
This worked on mine (the switch was worn), but the best solution was when I bought and fitted a new switch unit.
