Overnight opening

My car is a 2006 Skoda Octavia 1.9 PD hatchback. My problem is that, on two occasions, all four windows have lowered to halfway overnight. On one of the nights, it was pouring with rain! I am not sure if the car was unlocked as well, as I had unlocked the car with the fob before I noticed that the windows were open.

I was wondering if it might be a problem with the fob – while it was in my pocket, I might have accidently sat on it and depressed a random selection of the buttons. I have tried to replicate this by pressing many combinations of the three buttons but with no success.

The reason I think it may be related to the fob is because there is apparently a function to close all the windows from the fob. Is this possible or could the problem lie elsewhere? Graham Moore

Pressing the unlock button and continuing to keep the button depressed after the vehicle has unlocked, should result in the windows being automatically opened. If the vehicle is unlocked by the fob, but a door is not then opened, the vehicle will relock itself, although the windows will not reset and the vehicle alarm will remain off.

The default time for this action is two seconds, but the dealer can adjust this to six seconds. The dealer can also deprogramme the global opening function, which may solve the problem.

The cause of the fault may also be the control module in the driver’s door. If this has been affected by damp it may be shorting out and causing the window opening system to operate.
