Removing Window Motor Gear Box Cover / Cleaning
Since 2 ongoing projects aren't enough, I decided to dive in and start cleaning out my slow-moving window motors.
I've found quite a few R&R threads, like this and this, but can't find any description of how to remove the gear box cover.
I've also searched on Google Images to see if different variants of the motor which have screws for the cover but couldn't find any of that side of the box (all of them show the gear side).
It looks like mine has compression pins (no clue what the right word is for them, but circled in the pic), so I'm guessing I either need to drill 'em out or pry the cover off, but both routes seem wrought with potential destruction.
Was thinking about soaking the box in something TBD (need to research) and then re-lubricate from the opening, but not sure how viable a solution that is.
Anything I'm missing? (which is likely the case).

I'm doing the same on a 944 window regulator and found the same pressed in pins. I drilled them out. No drama. There was plenty of dried up grease to clean out. I replaced with the same grease I use on wheel bearings. I plan to hold the cover on by mixing up some 2 part epoxy and drizzling into the drilled out holes. Haven't done this yet but don't anticipate any problems.

Thanks, Harvey.
I played around with it a bit last night, and the pins popped out (actually broke, but end result is the same).
Found things were dried up inside mine, too, so got some clean-up ahead of me.

I have just removed the window regulator motor/gearbox assembly with the intent of rebuilding the motor. There many great write-ups on this subject.
The problem I am having separating the motor from the gearbox. I have removed the two torx screws but can only move the motor away from the gearbox a few millimeters. Most previous posts look like this hasn't been a problem - separating the two.
Do I have to split the gearbox open? Mine has the pins, too.

Mine separated without taking the cover off. Just took a bit of wiggling to get it out.
Might want to rotate the external gear a bit while wiggling to see if that helps.

I guess I jumped the gun. Just a little more wiggle and it popped out. Surprisingly, the grease was still pliable and light amber color. This is my low mileage 83. Now for the motor rebuild!
