When I did them in my 72 Bus, I had to pay special attention to the cable cleaning, i thought mine were not going up all the way as well. Turned out to be a combination of 30 year old grease in the channel and paying careful attention to exactly where the motor is installed in relation to the register travel, I.E. you may have it hooked up with the register too far extended or retracted.

So I did this mod yesterday and there was one thing I didn't realize until I was balls deep in the project. If you want to use the mounting bolts on the motors, you can't use the method outlined above where you trim the old regulator and use it to lock the tube down.

First are couple of shots of removing the vent wing, which has to be done.
Removing lower bolt

pry back felt and remove screw. Tab can be bent and window tipped back. Also good to remove the spring clip felt retainer

This I why you must at least lift up the vent. See the tube running between the mount and the lower part of the vent frame?

You can get away just raising it up a bit, like so

OK here is the issue. Here is the right door regulator. See the locating nubs on the tube. They face into the bus when it's installed.

Now if you install the tube with the nubs facing out so that you can put your newly made retainer plate on, then bolt on the cover.... see the problem. The regulator mounting bolts are pointing out from the bus, not in.

(This is the left door, but same applies)

(Here is the right side one) Mounting studs pointing out.
From the first posts it looks like the OP set it up with the nubs facing in to the motor, that way the mounting bolts could be used. Down side was the tube wasn't secure, needed bending or welding. In this second method, just so others are aware (I sure didn't notice) you will have to mount the motors differently (that's what I did) or maybe you could try to grind new pockets into the back of the motor housing to accept the nubs so they can point inwards.
Anyway just a PSA.
I just did this.

Took me a few tries, but I was able to find an aftermarket part number. If someone can translate that into a BMW part number that would make this project much easier (because these are out of stock everywhere)

Gday all. westyracer started me on this path for fast glass. his thread was really informative. I did this video as a follow up to his thread. notchboy VWdubbers never ask or have stupid question. If you have alook at my 4x4 T2 conversion then you can ask stupid questions.

Ok found screw under felt. For those wondering its under the top portion near the upright of the windwing main window side, easiest method is to flex the felt window insert about midway along the top, this will allow you to pop out the whole top portion with the metal clips still intact, assuming you still have the clips. You can then proceed with removing the weatherstipping andsliding the windwind upand out at an angle to make a gap to free the window crank.

I know have a knew dilema, the crank i took was from an 83 BMW, and looks exactly the same as the one in the OP pics, accept the wiring. It has the black and blue wires that go to the motor, then another 3, one which is Yellow/Black, one which is Blue/Green, and one which is Green/Blue. When i ground the Black/Yellow wire and give power to the Blue/green, the motor turns automatically and will stop if either button is pressed (up or down). When the Green/Blue (slightly thinner gauge btw) is given power only the down button works. Same behavior on both motors (was assuming i mayby had a bad motor).

Any Ideas on that years wiring?

FRUSTRATED!!!!!

SOB!!!! Where the hell is the little screw for the weatherstrip? I finally managed to get all the pieces (motors, wiring, switches) but I cannot for the life of me get the damn crank out. Got everything unscrewed, got window dropped and actually mangled the damn felt so bad on the window side (vertical piece lining channel parallel to the wind wing) i'm gonna have to replace it. Really hoping someone will post detailed instructions on how to remove the crank and regulator.
