I'm going from memory so I may miss something, but I believe you do the following:
for rear doors:
- remove inner panel.
- roll window down, and unbolt the two bolts holding the glass in place
- carefully pull back the weather stripping from the top back corner
- remove top screw and bolts holding the metal brace between the window and back quarter window
- carefully remove glass
- slowly work the quarterglass out [it should basically pull out but needs coaxing for it to come
for front doors:
- remove inner panel
- roll window down, but not all the way down
- unbolt the two bolts holding the glass in place
- roll the window the rest of the way down
- carefully tilt the glass forward bring the back end up
- take your time and work the glass up until it comes out [it'll come out on the outside of the door frame]
be careful with putting it back in, or it won't work properly when you roll it up. Trick is to get it into place, bolt it in snuggly. Then roll it up until it's approx 3" from the top. Then tilt it all the way into the back of the frame and then tightened up the bolts. If you don't do this, when you roll it up, it won't fit in properly and end up on the outside of the weatherstripping.
Hope this helps. Good luck!
