124 '90 Dead Sunroof


It seems my sunroof has finally gone on the disabled list.

Here’s what is happening and not happening.

Using since the roof is not moving, I tried using the emergency nut and confirmed the roof does move backwards and forwards. However, the tilt mechanism is not working. The roof goes up about ¼ of an inch and then I here and feel a clicking noise. Like the cable is slipping.

Before dying, the sunroof tilted less and less. It finally died while closing and I had to use the emrgency nut to close it.

Motor does get power as I can hear the motor try to move the roof – one small click.

Roof did not seem like it moved slowly when it worked. Also, the clicking noise would be heard when tilting the roof upwards at the stopping point. I might add that it probably needed some timing work as the roof would not stop at the close position. It would continue on to the tilt up position.

Any suggestions on how to proceed? Not afraid of doing some things myself and I have found this forum to be most useful. Thanks to all the members for their input, I’ve come to enjoy my 300E from a mechanical perspective in addition to driving it.

Agree with FAD. This is, by all accounts, NOT a DIY project. There is great potential to screw things up in a big way. This is the time to find out who is the most experienced MB sunroof guru in your area. It is likely this person will be at an independent shop rather than the dealership.

Just changed the cable for my sunroof last week and it was an easy job, if you have the cd's if not i'm sure we can talk you though it!
Once you get the headliner out you will see if the cable is bent or broken. Mine was all bent up. You will also see if everthing is sliding the way it should be. The headliner came out and went back in very easy. The cable was a little pricey about 100 cdn. or 45 us.

Thanks for the replies.

I do have the CDs and plan on having a go at the sunroof tomorrow. We'll see what I find. Cables here are about $45.

If not the cable, I'd be interested in hearing more suggestions.

Kind regards,
