Could it be a split wire inbetween the door/pillar or something more serious?

When i unlock the car the windows go down aswell i know they usuall go down if you hold the button down on the key fob but im talking 1 click and windows are down,ok in this weather.......but its a problem if its raining!

Some times the car will just unlock as normal and windows will go down when they feel like it.hera are what i got with vag-com
