Possible cheap fix for failed window regulator
It's a bit hard to tell from the small picture, but this $10 part may actually be the same part of the window regulator assembly that we've all had to replace (twice in my case).
Instead of spending $60++ for a new assembly, when it is always the cheap plastic roller tip that fails.
*rear* window regulator ailments. it is really that inexpensive. but there is
a catch. it's not a plug and play part. it is also the solution ONLY if, upon
examination of the broken rear regulator, that the white plastic piece which
hold both ends of the cable, has fractured.
the item you linked requires that you drill out that metal pin/rivet first.
you then drill out the pin on the failed part on your existing regulator.
swap the broken white piece and replace using the new, green piece and
reinstall a new pin/rivet.
the task of drilling out two rivets, sourcing a replacement, reattaching with
new rivets etc may initially take 2+ hrs. once you have all this scoped out,
any future fixes for this same problem may take .5 hr.

some folks will simply buy a non-MB replacement off Ebay and pay about $40
in the process, getting the whole new regular arm, plastic fittings, and strand
cable.
the motor is usually not included and if it does, the price will hover $100+.
if the old motor is otherwise still functional (and it usually is), just unscrew
and mount it on your new regulator arm. a 1-2 min job
I guess if you're drilling out the old regulator in the first place, may as well just get the aftermarket assembly. Worked for me for about 5 years so far. But I figured if somebody really wanted to save a buck...
Speaking of which, anyone drilling out the OEM steel rivets should use a corded drill. Mine died, so I used an 18 volt cordless the second time at the dance, and I went from 7 minutes to over an hour getting out the three rivets. In the dead of winter to boot.
when someone posts e.g. "I'm going to buy one of the cheap rear regulators
on Ebay for $50..." someone is sure to recommend that they should stick
with a quality item [sic] such as OEM/Mercedes unit.
uhm....hello, foo. guess which manuf has a well established record of failing
window regulators? yup, the MB, OEM part.

I've never read anyone recommending the MB part but if they did, they need some help.

THe rear windows rarely get used in my car, but this weekend I drove my mother in law to a show and she wanted the windows down a bit. Now- after two years I once again used the remote to shut all the windows on a hot day - and BANG the left rear broke. I should have bought regulators for both sides last time.
Is there some issue with using the remote closing that increases the risk of damage???

I'm all about buying OEM parts, except of course when the OEM parts suck and caused the problem in the first place. Happy Labor Day everyone

Wife borrowed my car today and just called saying she heard a snap and the rear window won't roll back up. I'm guessing it's this little gem.
Any info would be great.
Tools you need - a drill to remove the steel rivets from the existing unit (3 rivets), a Philips screw-driver (preferably magnetic for when you go to put the screws back in where you took them out, some flat pry tool such as a thin drywall tool, a rivet gun from Home Depot + a pack of aluminum rivets.
Goop to reseal the plastic vapor barrier - someone else needs to opine. Silicone caulk?
