This sunroof discussion is helpful as well as scary. I really like the tilt feature and use it almost exclusively. Does anyone know if the slide function works when the tilt arm breaks? Will it close when it breaks? Thanks, Dwight
Dunno, depends on it's position when it breaks, I guess. There is a special tool to manually close the sunroof should it break. Below is an old post on the subject. For this reason, I've never used the tilt feature on any of my cars so equipped.
Tom [MB] sunroof not working on 126 (300 SDL) Bill Brandt wlb at lanset.com Wed Feb 20 18:28:04 MST 2002 I might add to what Richard has said - I recently had to have my 86 300E sunroof repaired and I remember enough from the list to not even consider trying to "fix it" myself - I took it to a good independent who has done several dozen of these and here is the summary of what I learned: 1. The pop up function is what breaks these sunroofs. The mechanism (frame) that stops the roof is basically pot metal (as original) and when you hit the tilt function there is no kill switch to stop the motor/pressure - and over the years this is what causes the breaks. 2. The newer parts are improved but still a compromise. 3. If you never use the tilt function your sunroof will last forever 4. If you try and fix it yourself, or continue to use it you will bend a tub that the cable is in between the headliner and roof and your repair bill goes up considerably. Worst case - they have to remove the headliner. 5. I got a $150 discount over the estimate for not making it worse once the symptoms developed...Sort of a "you didn't screw it up worse" discount ;-) 6. Ernie (Ernst) said that I can use the pop up function with the new/improved parts - just be aware that that as long as you hold the switch it is applying pressure. No cut off once the stop is reached. Personally I wish they hadn't come out with this "pop up" feature - but there you have it... Bill Mike Ohlman said: "any words of wisdom on why the sunroof quit working on my 87 300 SDL? The pop up function will work, but when you try to open it in the normal fashion the passenger side drops down but the drivers side stays fully up. If you keep holding the switch the fuse will blow. Any BTDT?" Good evening, Mike -- Check the archives. I posted a long post about it several years ago after my wrestling match. Don't remember what all I said, but the gist was: "the learning curve is way to high to scale for a DIYer and the benefits (one sunroof repair every 15 years) are not worth the ascent." Oh yeah, this applies only to post-86 MBs (the sliding-only tops are a POC (piece of cake) compared to the Rube Goldberg-inspired pop-up sunroofs). A tip while we're on the subject: to ensure longevity of post-86s, manuall assist the rear when you utilize the pop-up feature. Stop the switch immediately when it is raised up. Same going down. Same front, same rear. They are "tender" and have a definite length of life.
