early vs. late - power window motors/regulators??

[StereoInstaller1]

Unfortunately, I cannot claim experience swapping late motors to early doors. I know it is do-able, but cannot offer advice.

If you do it, post some pics! I do have a set of late regulators sitting around, and the (early) ones that are in my doors now are dead slow. I dread swapping them AGAIN, for like the 4th time, unless I go late model. For now, mine work.

Is there fabrication involved in switching, or does the entire system swap over if you do it complete? The door cut-outs & holes appear the same at first glance.

Thanks for the comment. Would prefer to fix this today, not have to go find/order another early motor.

How does the actual glass release from the late regulator track? I dn't see any bolts. Where the glass sits in the channel on the two locations, just see two tiny holes drilled inthe aluminum channel, appearing to hold clips

Early and late are different, the motors have different splines. Also the early design is a cork screw type inside a rail that spins where the late design has arms that pivot off each other. (seta is early design).

Best bet is to grab a used early and use that. I would suggest getting 2 of them because my car has gone through 3 of them on the passenger side. I'd take the rail out and clean then re-lube it to reduce any friction for the motor.

No fucking way. Get your fab skills out, do something better.

The early design is shit: in fact, I bet your motor is OK, but the damn hub wears on the worm drive crap and binds so bad it can't move, faking a dead motor.

Ask me how I know...

IF you have the chops, swap to the late mechanism. Much smoother, quieter, quicker. My '87 will get late doors before paint...even though I have the chops to swap, I choose to have it appear factory.

Late door panels, too, IMO.

GL!

OK. I have searched, both here and on Google. I have the Bentley. And I still need some pointers... Please.

86 es, passenger power window doesn't operate. 91 325i parts car with good window operation. I have both door cards off. I have 12v to the motor of the 86, so I'm pointed towards the motor being defective.

With both door cards off, there is obviously an early & late system of regulator/motor mounting. What is the best approach? Swap out the entire
regulator system? (I'd lose the optional hex-key cranking sytem) Are the motors the same/interchangeable, even though they are mounted differently? Should I pull 86 motor and try to clean up the internals?

Any advise (or point me towards applicable threads) appreciated.
