i have a 05 renault laguna. i done some work on the car which i had to disconnect the battery.
when i connected the battery back up everything was ok apart for the electric windows would only just move a small way about 2 inches at a time.
so what i did was to put the card key in the slot and started the engine then with the miles showing on the on the clock i pressed in and held the computer button on the end of the wiper stalk for about 20 seconds then operated the problem window but on my car i had to do it four times once for each window..
