Here are the steps with pictures of what I did for the second window. Thinking the first effort may have been a fluke, I thought the second will confirm what happened.
Tools and Set-up of an old Black and Decker Workmate with Wood Block.
Slick 50 silicone oil
Small rubber mallet
Thin spatula, razor blade, thin blade putty tool, anything to get between the rubberís interface.
Second Window Steps
1. I heated up the length of the channel for about 2-3 minutes until the channel became hot enough that I saw a little smoke and smelled a faint whiff of burning rubber.
2. I squirted some oil on both sides of the window.
3. I used the blade tool and tried to work in some oil between the metal and rubber, not the glass. I favored the ends. I didnít spend more than 2-3 minutes on this step.
4. I put the track over the wood and then pounded the edges of the glass firm, but not as hard as I might think the glass would break. I tapped multiple times, tap, tap, and tap on each side, like a jack hammer.
5. I checked the edges to see if any movement was observed on one side or the other and then repeated Step 4, probably about 3 times.
6. Once I saw movement, I was able to grab the glass by hand and tilted away from the channel to remove. Hereís where the screwdriver prying worked with the first window. The second window came out a lot easier.
Note in pic #3 that the rubber again stayed with the glass when the window came out. A glistening sheen of oil could be seen 1/2 way down the interface of the rubber to the channel. I suspect it wicked into places that helped.
So how long did the second one take? About 10 minutes. So the average time to remove the glass from both door channels was about 3/4 of a day. I suppose itís kind of like a man drowning in a pool with an average depth of 6 inches, i.e. 6 feet at one end and 1 inch on the other.
I hope this helps someone else do what I did in less than an hour without drowning!
