respond

My electric windows will sometimes not respond when I try to roll them back up (have not noticed the non-responsiveness when trying to roll down). I usually give the drivers side door a gentle tap or 2 on the side near the buttons and they respond. Anyone else? Any advice on what I should do...

The administrator wont respond to my messages as I have asked why his forum only sends out notifications on sunday night . This doesn't keep the threads going well with responses. I belong to a lot of other forums and this is the only one that does this . What gives???
