Hmmmm. There are a couple of Torx screws as I mentioned, but the housing itself looks sealed. I don't see any other fasteners anywhere else other than rivets.

I decided just to spring for a new motor, because I want to get this done ASAP and move on to bigger projects. The OE part is anywhere from $300-$400, which is crazy. THE OEM Bosch part was discontinued in 2013 and is NLA. eBay is full of salvaged parts that are cheap, to be sure, but could fail tomorrow for all anyone knows. I finally settled on a reman from AutoZone because it should be delivered to my front door by the end of the week, and it was only about $100 with free shipping, a 10% off coupon, and the core charge refund. Maybe it won't last another 25 years, but I suspect I'll have bigger problems before then anyway, lol.

BONUS ROUND! There are a few things I still don't get. One is this extra slider, item #1 in the picture below. It was just sitting there, in the window rail, not attached to anything. It's shown in the EPC diagram - but again, not attached to anything - which is odd - surely it serves some function? #2 is a body-colored vertical rail. Is that just structural reinforcement, or is there supposed to be a slider in there? FOr example, item #3. Clearly some sort of slider, same plastic as the others and greased up the same as well. I found it loose in the bottom of the door. That can't be good, right? lol
