    I know this sounds weird, but I found my car with all 4 (electric) windows wide open yesterday, after having left it in supermarket carpark for 30 min.

    I know I didn't leave them open, had the aircon on, my passenger is also absolutely sure about this.

    Nothing taken from the car. Radio and clock still working, so no interruption to power supply (wouldn't make sense that that would open windows anyway).

    You have to press 4 buttons to open 4 windows, I can press 2 at once but not 4, impossible to have done it accidentally.

    Completely baffled. :confused:

    Any ideas what might have happened?

    Hi
    Our AA Patrols see this quite often on all sorts of cars. It's often caused by water in an ECU and stops happening when the ECU dries out. It also causes odd buzzing noises from relays and self-activation of electrical items. One Patrol went out to a MPV and all the windows were going up and down with no one near the car.

    You think it's a fault then, rather than me pressing the unlock for too long? It did seem a reasonable explanation. It hasn't happened again - yet!
    If it happens a second time then maybe you will have to consider the possibilty. Let's hope it doesn't.

    Dumb question: what's and ECU? how does the water get into it?
    It still hasn't happened again, fortunately, and I quite like to be able to lower the windows on hot days on my way back to the car now :D
