My vec c would do this, and as in the vid it was the abs plug, wd40 to the rescue. Abs, tc, indicators immobiliser and dash functions all go through the cim and for some reason the abs plug has a big affect over it. But as for the windows???
After disconnecting the power you have to reset the auto functions of the windows but they should still go up and down with your finger held on the button. Try holding your finger on the unlock button of your key fob, the windows should go down and if you hold down the lock button they should go up.
