In case anybody checking this thread is looking for one, I have a new 116 OEM driver door power window regulator still in the original packaging...

You know your picture pretty clearly shows a 116 part number, not 123?

Look it up. It goes on the W123.

Hmm, so I guess rear regulators are the same between 116 and 123. That's good news, since I was looking for a set of manual rear regulators for my 123 wagon and have 116 ones lying around. Will have to try and see if they fit.

The part number assigned begins with the first chassis a part was used on.

There are parts on a w123 that start with 115 because they were first used on a 115.

Yeah, I know that, but I thought I'd seen rear 123 regulators with 123 part numbers. And actually, it may well be a different part number for manual regulators simply because the attachment for the crank was changed from using a screw on the 116 to a simple clip on 123, though for power windows this would not be relevant. Anyways my mistake to point out that it was a 116 part number in the pictures.

I believe the rear window regulators for a W123 coupe begin with the part number 126.

Thanx for that heads up ! .

I simply never lower them and don't allow Passengers to touch the buttons .

I am the only one that can exercise mine - about once a month. No one else is allowed to touch them.
