I did this around 9/20/2010 on pass front. Gotta do the DR rear now... Fun is.... NOT.

-ALF out....
just did driver window today.
one thing, i probably over reacted to this, but, i really did not want to stick my hand in there... especially with the auto down feature, on the driver door...while batt was live. So, I got it into position, then removed the batt cables, (neg first off, then neg last on), each time, before doing any work in there. Just me over reacting I'm sure, but kinda how I'm wired.
to it: used long needle nose to bend (lightly pry) the rear end of track open, slid two new rollers in from the back (they seemed like they would not go in, but used the end of channel locks (rubber handle), and pried them in... (pried agains the edge of the rear cut out) pop! they went over the rivit in the channel, no worse for wear. I scrubbed the channel as best i could to removed old grease, and re-greases. I lined up the "balls" and used channel locks on one, small c-clamp on the other. did not remove arm rest. got all done, went to test it, but had front of driver (from when popped both of the old ones off...keep your hand on the window, so it doesn't fall), but when that happened, the front window must have slid out of the rubber/felt channel in the front. uhg. had to pop front one (front) out again, and re-align. popped ball it back in. I did hit the new rollers, (while in the channel), with a hair dryer for 2-3 min., before popping them in... could not tell if it helped, but believe it did. Did not even know about third slider... (panel still off, so will check it).
my experience, the panels are the most important thing, like others have done, i sawed the bottom two plastic clips off (pulled hack-saw blade out of my hacksaw, put some tape on the end like a handle and tah-dahh cut thru the bottom two)... this panel is my second one... had to find a replacement, (ebay $$) as the plastic was damaged beyond repair, the areas that hold the clips, leaving bottom of panel loose. (i think just from years of shutting it, over and over again, or dealer doing the job, (they did once years ago) ...the tech doing it, may not have had as much concern for the panel, etc...as an owner would. prying those clips off... against a plastic door panel is a crap shoot (IMHO)... the panel is so fragile, so cut bottom two, and the rest were nice, and came out with pry tool, it was flat and had a channel in it with a handle on the end. worked okay.
the biggest issues for me, that require the most care, at least for me, is the electrical connections, take your time, and be careful to pull them apart. some are easy, others, took a while (need a third hand, to hold the clip open, and have enough hand strength to pull them apart. eventually got them.
... and watch the window to be sure it's in the groove before you snap those in ;-P
thank you to everyone for their thoughts and tips, this site is amazing. (I also have the Qualoss paper... that is pulitzer material to me ;-) window works well now.
(my main reason for doing it straight away, (broke on Friday) was smoking cigars in the car.. gotta have a working window ;-)
thanks again to all.
