100 Series Electric Window Switch works spasmodic

Sounds like the switch, the drivers side usually is the first to go as it gets more of a work out. There is one on ebay $270 not hard to replace.

I had the switch out of my 80 series today (they look the same as my 100 series). Any....it is a rocker set up with a contact (like the old pinots set up in distributors). Miy 80 series was playing up like yours, and I just used a points file on the contact and it works fine this arvo. I would say you will sonme arcing around the contacts and plastic moulding. Pry the plastic swith holder out, and switch will pull apart by taking out a couple of phlips screws. Just watch the little springs in there.
