thanks for all the info guys. the splines are fine i removed the winder and that part is ok. in the bottom of the door i found what looks like an old track so it looks like an arm or something has come off. i cant seem to get to the glass from the bottom and trying to push the glass up from the top access hole dont work either.
i shall take another look in the morning to see if i can free it up. there is a used rergulator on ebay for $35 mabye i should just buy that.
is it easy to remove the old regulator and glass?
