remove inner door panel and triangle piece behind the mirror
peel back the plastic liner so you have access to both sides of the inner door
roll the window about 3/4 of the way down
starting along the top edge, pull out the old glass run channel... you should be able to start it pretty easy from the center of the top of the window... pull it slowly and steadily so you don't break it... it should come out in one piece... it might not
CAREFULLY pull the channel up and out of one side of the window track... be careful... the window will be loose and free to move around without the channel keeping it in place
then even more CAREFULLY pull out the other side... the window will be VERY loose... don't let it come out of its track... if it does, set it back in place or you won't be able to get the new channel in
starting at one end put the new seal into the track and slowly feed it down until you get to the edge of the window... it will a tight fit to get it over the edge of the window and sliding the rest of the way (some silicone lube sprayed in the window channel will make it slide much easier) keep sliding the channel down until you get the top corner where it goes.... make sure you jam the corner up in there tightly
now go to the other end and feed it down the track... this will be pretty much the same as before, but it is going to be a LOT tighter since the glass isn't loose anymore (again some silicone spray lube will make this easier)
now press the top edge of the channel into place and make sure that everything is tight, lined up and in place correctly
if you have power windows get your door panel and hook the window switch back up... make sure the window moves up and down smoothly and without obstruction
press the plastic liner back on to the adhesive putty
put the door panel back on
put the mirror triangle back on
go wash up
i like to clean and lubricate the window channels from time to time... spray a decent amount of silicone lubricant into the channel... put your finger in a rag and run it up and down the channel to clean out any crud (you may need to do a few passes)... then spray a light coat of silicone lube and leave it there... this conditions the rubber and keeps it nice and soft... it also lubricates the channel reducing drag between the window and the rubber, makes the windows move smooth and quickly, and reduces stress on the window motor (or effort it takes to manually crank them)
