Thumbs down c230 Leaking sunroof

Just happened up a nice used c230 Kompressor - Has some minor electrical issues - I'm new to this site and forum sites in general. Figured I would give it a go. The sunroof is stuck closed. Fuse appears to be good. Need to find a way to open the sunroof so I can get to the drains. I have a bad leak, and believe it has to do with the sunroofs drains being clogged. Any Ideas>

If i am right you do have a manual roof opener some place . But it might mean removing the head lining that just covers the sliding panal in the roof. Welcome to you by the way . And hope you find what you need . Members will help you as they drift through.. When you get to the drain holes dont push items down the hole that are to large , it can dislodge the drain pipe .

Thanks a bunch - new to MB

Thanks so much, love this car, trying to figure out if that is the source of the leak. Know of any other places that water may come in? The guy I got the car from had to take the interior apart to get the 5 gallons of water out. He had to go through all wiring and harnesses. Not sure if it is a fuse or if the sunroof uses a relay.

Leaf matter will get everywhere Jonathan.

Look in around the engine bay and down near where the bonnet hinges are and the drains around the wipers and front of the windscreen.

There are nooks and crannies everywhere and if you are in a leafy suburb with a damp climate, you will strike trouble at some point. I had a W123 that always filled up with water on the back floor after a deluge and the cause was coming from within the engine bay. (I don't know how or why ???) Once I cleared it (and it took ages and the debris looked like mud) no more problems.

To be honest I doubt it's the Sunroof where the leak is, because you would see water dipping into the Cabin if it was watertight.

The sunroof can easily be opened and closed manually. You remove the Overhead Control Panel and use an Allen wrench crank handle (which included in the car's tool kit) to manual operate it. Instructions are in your owner's manual. If you don't have one, you can download it from the Owner's Section on mbusa.com.

Smile Thanks for all the replys

Well, i think you guys were right; the sunroof is probably not the problem. I did manage to get it open using an allen wrench. However, closing it was quite a different story. The metal they used stripped upon cranking it closed. So at a loss, I decided to switch around the sunroof shade and sunroof motor connectors and managed to get it closed that way. What a pain. Today I will tackle the area under the hood. I noticed that the plastic cover under the windshield wipers that fits into the grove at the base of the windshield is not seated right. I think that may be the problem. Hopefully that solves the problem. I thank you all for your input. What a great community I have stumbled upon. Thanks!!!

Oh, you have a coupe with the panorama roof? There is a common failure where the motor that drives the glass doesn't fully engage its gears. Search the forum - there have been some fixes posted.
