Mercedes-Benz W123 drain cleaning, part 1 (firewall and sunroof)

In this two-part video, Michael will demonstrate how to clean EVERY drain on your Mercedes-Benz W123 sedan. The rear sunroof drain isn't something that clogs easily, so you won't find much on it. When it does, however, Michael demonstrates how to access it.

Thank you for all your videos! Please do a video on chasing down vacuum leaks for the car door locks!

[@michaelthemercedesguy]

Thanks for your support! The next time I get a car in the shop with a vacuum leak we'll try to film it.

Thanks. Looking forward to part 2.

Great video, thanks, but... You kinda slipped right over the rear sunroof drain... Is it easily accessible with the lid attached?

[@MrTopherlicious]

Where do the rear sunroof drains exit? would it be possible to clean from the exit? I don't feel like removing my headliner

[@georgecurtis6463]

Just use a length of speedo cable in a drill at slow speed.

Good job

Great video. I also watched the 2nd one. My dad's mercedes c200 1977 w123, has water in the passenger side rear footwell and rust on either side of that passenger side rear arch (front and back) . I unblocked the hole in the side of the boot as your part 2 video. Looking atr the rear passenger door, there are slits behind the half triangle rear mirror which were filled with bamboo leaves but there seems to be a fibre in those slits are they meant to be empty and where do they drain to please?

[@michaelthemercedesguy]

On each side of the car the oval air vents under the bright trim next to the back window are for air to escape the interior. They do not have water drains, and they should not have any fibrous material in them. If they do, it should be cleaned out.

[@tarunarya1780]

@@michaelthemercedesguy thanks for replying. I will clean them out

[@marthaboyd9937]

My 85 300td station wagon leaks by gas pedal when it rains - are there other drains I need to check other than the two under the hood you show?

[@michaelthemercedesguy]

No, there aren't any other drains on a W123. The only other possibility is that your windshield seal needs to be replaced.
