I hold the electric window button till it hits the lower limit then hold down for 10 seconds then same for up. This cures it 8 out of 10 times. 2 out of 10 I have to repeat the rest cycle 2, 3,4 or even 10 times and mostly it will eventually reset to normal. Once or twice however, it just won't reset no matter what you do eg. turn off and start again, do it with engine running, with engine not running, locking the car completely and starting from scratch, standing on one leg, singing incantations to the full moon, and just about everything else. Then the next day it resets on the first go. So no logic to it. This last time I haven't been able to reset for the last 7 days or so. But as I say the last two days were dry and the previous 7 days were all wet. Thanks for staying with me on this one.
