Dave,
Remove the door trim and interior latch and window winder hardware, enough
to give you access to the inside of the door.
Just below the vent window pivot point (inside the door) you will see
a bolt with a spring, washer and nylock nut assembly. Using a small 5/16 inch
socket or box end/open end wrench remove the nut from the pivot bolt. Be
careful not to loose the hardware into the inside of the door. If you do, it is
likely to get stuck on the door hinge platform in the upper front interior area
of the door, where it is a struggle to retrieve. (past experience).
Before attempting to remove the nut I would soak the bolt shaft, spring and nut
with WD40 or liquid wrench, it rusts pretty good over the years and it will
ease the removal of the nut and spring.
Now with the nut, spring and washer removed, open the vent window and wiggle it
open close/open close etc. lifting the window at the same time. It should lift
right out. Once you have it out, you have access to the rubber to replace it.
You may want to remove the chrome trim piece that fills the gap in the front
lower corner of the vent window frame this may help in the checking that you
have the new seal installed correctly. The trim piece is held in place by
three small sheet metal screws. One on the front edge which is countersunk and
then one inside and one outside, both dome headed. These screws are really
short, don't loose them into the door abiss!
To install the new rubber you will need some sort of lubricant to assist in the
installation, I use dish soap. Begin by installing the lower edge first so as
to line up the hole for the pivot.
While the vent window is out it gives an opportunity for you to clean up the
pivot and spring. I grease this up pretty well during assembly.
Use the reverse procedure to put everything back together.
The compression spring on the pivot bolt gives the window the resistance to
stay open while the vehicle is in motion. A judgment call is needed to give
this window the necessary working resistance.
Just enough tension to keep the window in a set position while the car is
moving.
You could compare the tension of one side window with the other.

I think I have covered everything, if I haven't I am confident someone will
pick up the slack and correct me. If you have any questions let me know. Good
luck john.
