2014 E350 drivers side window switch issue

Hello All and thanks in advance for everyone’s help

I have a 2014 e350 and the problem I am having is intermittent.

When I press the drivers side window switch up to roll up the windows the switch does the opposite and rolls the window down. It actually rolls the windows down in the automatic down position all the way to the bottom.

This doesn’t happen all the time but it does happen frequently.

Anyone have this problem?

something get spilled on/near the switch?

I've had similar issues with much older cars, and had to take the door card off, remove and disassemble the window switches, and clean them off with DeOxit or another contact cleaner

Try re-initializing and make sure the window track is clean.
