2002 SL500 Windows automatically roll down when turning off car

Hey guys,

Having an odd issue with my 2002 SL500. When I shut the ignition off, and remove the key, all is normal. As soon as I close the driver door and
walk away from the car, both windows automatically roll down. This is whether I push any lock/unlock buttons or leave the key open or fold it.

At the same time I hear something actuating in the trunk. I have no idea why the windows keep rolling down but would like to figure it out. The
issue is also intermittent with no consistency.

Anyone run into this issue before, or know in which direction I should start to go to resolve the issue?

Thanks,

-R

Unfortunately I only have the one key, so I could not rule out the key as the issue. :/

You can rule out the key as the issue if you remove the batteries and manually lock the car with the blade

Try the reset technique.
Driver window down and hold for 10 seconds. Up and hold for 10 seconds.
Repeat for passenger side.
