Auto Glass: 84 chevy C10, C10 door glass, Vent Glass

Question
replacing  driver side glass window vent
Cant seem to get it off.So I removed the door panel to get to it from underneath  to remove the while frame, but no wrench can get through the door panel. Do I need a special tool? or am i just going about it the wrong way. If you can't help please guide me in the right direction.

Answer
Hi Hector,  

         There should be two bolts that line up with the vent channel that goes all the way to the bottom of the door. One at the top and one near the bottom. Once you remove them the vent assembly will be loose and the window must be in the down position to remove the vent assembly and don't forget the screws that hold the very top of the vent from the outside of the door frame. Replace whole frame in reverse and lube window regulator.No special tools required. Hope this helps!  Stay safe! Derek : )
