Very informative post! Our 126 has the thumping regulator on the front passenger-side window. After replacing the rectangular plastic sliders in both rear windows, thought I'd dig into this one. Didn't ruin anything removing the door card, whew, noticed the top nut in that metal indent was missing.

Found it and the white plastic spacers in the bottom of the door. Using some garage engineering, used a longer bolt and two washers, one on the backside of the regulator and one on door panel. Plus, I reused the boogered-up white spacers in between. That hole in the door panel had grown a bit. This is a temporary fix, at least the motor assembledge isn't warping when using the window. But, there are teeth missing, and the window stops about a half-inch from the top. One can use two hands though, and push it up! Beer up.

when I got my '82 126 the rear windows would fall down and had to be raised by pushing them up. The slide jaws were smashed and the regulators were bent. straightened the regulators and riveted on the new jaws. has been fine ever since. My window switches stick for the rear and sometimes I don't realize they have been pressed.

It doesn't matter if you know what you're doing, as long as you look like you know what you're doing.

I know the W123 front regulators got a redesigned & strengthened casting somtime in the early '80s. At least that was the case 12 years ago, when I got a used one to replace the twisted & broken driver's regulator on a '79 300D. Don't know if the same applies to the W126.
As for the 240D, I've owwned two with power-windows!

Happy Motoring, Mark

If some type of switch could be installed, so when the window nears the top it would stop the motor.
I saw this switch on a 190E today in PNP and searched the # 002 545 01 14, and it comes up as a W0133-1623395 here in Fast lane.

maybe something like this could work?




My 85 300D had one of these on the VC that did something?

Why utilize another piece of technology when a properly educated and capable driver fulfills the requirement completely?

Of course, if you're incapable.............maybe a Honda or a Toyota would be more suitable.

I took the button class and have been certified.

I posted that for the button challenged individual.

He's taken the online class and is now proficient in button operation. He doesn't need that electrical switch.

Brian still can't bring himself to admit that the car came with a SLUGGISH right rear window that experienced strain throughout its range of movement!

Due in part to not one but TWO layers of window tint....now removed to pass inspection.

I fully admit it, after the fact.

Unfortunately, I didn't know it because I had limited opportunity to use that window.

This is part of the irony of power windows. With some other forum members, I believe that the less they're used, the more prone they are to failure.

The tint didn't impede the operation of the window on the LR. Now, the RR window had the tint falling off, so you'd have a good argument for that one. But, surprisingly, the RR window worked fine, even with the delaminating tint.

The tint on those windows was really garbage.

They let me keep the tint on the rear....they cut us some slack in RI so as not to damage the defroster.

That's good news. The tint on the rear is probably the best of them all...........

I didn't think "slack" was part of the vocabulary of a government employee...........??

I can`t win. Sad Trombone
