Hi, My drivers side elec window button isn't working as it should. It doesn't go down by itself when I press it down all the way (ie through both clicks). I need to give it a seriously hard press, and then it does go all the way down on its own. It works perfectly for the closing, so I'm guessing that it's just some dirt in the switch. Does anybody have any suggestions to fix it. I don't want to strip the door card off, do you think a squirt of wd40 will work, or will it wreck the soft rubber covering on the switch?
