The tilt mechanism on my 88 420sel tilts completely on the drivers side and only partially on the the passenger side. Initially it barely moved but it has started to move a little more since I started using this feature. Is there an easy way to lubricate this feature? Did the sunroof tracks this weekend and the the roof glides much easier now. Just got to get that tilt mechanism to work.

Also the wind deflector won't pop up. I manually have to lift and lower it. Any hints on how to fix that.

The deflector is probably stuck and needs lubrication. Squirt some silicone spray lube in all the pivot points and see if you can get it to go up and down. My advice is NEVER use the tilt feature. Using the tilt feature greatly increases the chance that you will have to learn how to dismantle the sunroof and replace very expensive parts. Be happy with a sunroof that opens, and perhaps more improtantly, closes. Also, in cold weather, do not use the sunroof. Charlie

Should have listened to you Charlie. I dropped the tilt and and tried to open the roof and something broke/jammed. :( The good news is at least the roof is in the closed position.

I must say there is one good thing about the sunroofs in my MB cars. They do not have the tilt feature and both work very well.

Of course, the sunroofs on my 98 Nissan Maxima and 99 Mazda 626 never gave me any trouble and they have sliding and tilt features. Maybe I have good luck with sunroofs. I owned plenty of vehicles with factory sunroofs and never had any problems with any of them.

Are sunroof failures common for our cars? I use my tilt all the time...love it...but now I'm scared.

I use my sunroof all the time, especially the tilt funtion. :)

It works well, you get efficient air circulation without the wind buffeting of an open sunroof.

Lubricate the sunroof slides, unclog the drains and you should be fine.

I've only had to re-set the gears for the sunroof (in trunk) once.

Is slicone spray lubricant used on the sunroof rails as well? I was thinking of using dry PTFE spray lubricant on my sunroof. It closes very slowly and also seems to stall a bit or get hung up. I have to drepress the sunroof switch in quick bursts so it will close.

Jonathan will sell you a small amount of the MB approved sunroof paste for a few dollars. Shoot him an email.

Since its on topic:

I fixed my sunroof a few weeks ago after the slide/lift arms had broken. Now when I push the close button all the way the sunroof closes but at the end tilts up. The tilt button isn't functioning either.

You need to re-set the gears behind the access panel in the trunk.

Do a search on the subject.

If you can't find the instructions, I think I have a write-up on my home computer.

I ended up messing around with the nob for a good half an hour before realizing that clicking it out twice did nothing because the knob wouldn't budge at all. Turning it after the first click didn't seem like it was doing anything and I couldn't figure out how to allign the knob with the allen wrench and my head started to hurt. So to see how things were going I asked my gf to push the button to see it it worked.

It went backwards just fine but when she tried to close it seemed like it was losing power and just stopped halfway open. At this point I got super pissed off and thought I had spent those 8 hours figuring out how to replace the gears was for nothing.

Then I realized that I could calibrate the knob and ended up doing a trial and error to get it perfectly alligned.

Thanks for the help!

I'm glad you figured it out.

It all seems a bit inexplicable at first, and it is also difficult to descrive exactly what you need to do without pictures.
