Obviously, too many displaced spacecraft & rocket Engineers have Infected the auto manufacturing industry…..Nothing like this design should have ever been used for road vehicles…..

You did an amazing job Ray!….I own a Mercedes commercial vehicle I repair myself, feel your pain. Perhaps an easier approach the next time you need to change a window regulator on one of these would be to cut an access hole from the outside of the door, with say a 9" grinder……There was a time when the three point logo stood for quality, now it just stands for overly complicated junk covered in bling.

I hate jobs like these, I had to do it on my wife's 2002 Buck Century. It was not really hard, but very tedious. She drives a 2020 Camry SE now and I hope it lasts because it looks a lot more complicated like most modern vehicles.

I get a weak feeling in my stomach whenever I watch somebody dredging around inside a door trying to repair a devilish mechanism that the door was assembled around.

4 days, 12 hours, 31 m in later the door panel was removed, along with the new regulator, etc Total Cost = $3,123 + tax and shop fees. Remember kids, if the door regualator repair is more than the cost of the vehicle you are a sh!thead 😂😂

great job so much work hero

Ray you should do more European cars you made me laugh in your first episode on the Mercedes when you didn’t tighten the wiper arm but it’s really satisfying watching the complicated cars be taken apart and put back together.

Nit-picking here but you forgot the two screw hole plugs that go at the bottom of the door. Also forgot to replace the sticker tape that covered a hole near the driver's door SAM.

Sort of job where you need some extra hands. Great video.

Interesting video. Makes me glad I only have a Honda Civic after removing my door panels to upgrade speakers last weekend lol. This looked like a pain.

Ray, this was NOT an uninteresting video. I love seeing how different manufacturers accomplish the same thing using different designs. Mercedes, while complicated, look really well made when you see the level of detail in that door panel. The sound insulation blanket vs a sheet of heavy plastic used as a liner is one difference. Plus, that door track mechanism looks way better than the one you replaced in the BMW some months ago while at the old shop. Granted, that was an aftermarket POS; I am referring to the basic design that MB has that looked structurally sounder. Just my opinion, of course! Keep those videos coming buddy!

Watch after all this trouble changing the regulator assembly, Rainman puts it all back together and finds out the window motors' nylon gears are stripped too! chalk one up for another "Rookie" mistake"

What the hell is all that grinding noise in the background? I thought this was your own private shop? Did you put your wife unit to work on body work on other cars?

I kinda suspect that the Mercedes dealership mechanics just change the door when the window regulators go bad

So you performed a very expensive job to "save" the cost of a $54 recalibration procedure?

While they are a pain. At least most things on at least older Mercedes are actually ment to be able to take apart and fix. I had an old one and the glove box light switch was easy to take completely parts and repair it.

When I worked at a body shop I’d run a razor down that black stuff. It’s called beutal and just slap some extra on it when jnstalling

I can appreciate your dealing with complexity. The job of maintaining my wife's beloved 560SL (88) falls on me (my personal thing is simple OLD Jeeps). Official service information is hard to find (and I suspect many dealer mechanics are younger than the car). Not to mention special tools (!!!). Some good stuff on Youtube and user forums, fortunately.

Spent a couple of months trying to resolve an idle issue which was eventually traced to idle control module buried so deep behind the glove box that I could not see it at all and had to remove it entirely by feel. Of course replacements are not available, but found a shop that rebuilt it for me. Frustrating, but wife is happy.

to stop the glass dropping on you, duct tape to the glass and over the top of the frame. It's more than strong enough to hold whilst you mess with the regulator.

For frameless windows, rubber door wdges work fairly well

The door is definetly not designed to be dissassembled
