Hi guys, my grandma died and I have her car to sell its a 1989 300SE in very very good condition with 107k and meticulously maintained.

The sunroof is electric, and the air dam? (the black flap that points up when the sunroof opens) does not go all the way down when the sunroof begins to close. THe sunroof gets jammed on the flap. Is there a way to adjust this so it lowers in time to slip into the sunroof like its supposed too? THanks!!

don't want to be negative..

....but why don't you just sell it with the minor issue... shouldn't really affect price much.

most on this board are reluctant to deal with sunroof issues...or we just don't have experience

the air dam is spring loaded. When the sunroof slides forward, the actual roof pushes down on the tabs, lowering the air dam. You kinda have to see how it works to understand it.

Its probably dry, and needs a good lube. Look very closely for any small broken pieces of plastic, but beware, sunroofs on the w124/126 are amazingly complex, and difficult to work on.

I had a similar issue years ago, and a bit if lithium grease resolved it.

Good luck, and post some pictures when the problem is resolved.

markho, sunroof adjustments require experience and skill due to the mechanical complexity. Recommend checking in your area for an indie who has both and is willing to work on the 1989 300SE sunroof. Ask for a repair estimate before leaving the car for service.

If you cannot find a competent indie to handle the adjustment a local MB dealer will be able to get it working properly.

i dont think grandma used the sunroof at all, so some lube may work. I understand how the mechanism works, and it seems as if there are adjusment screws. i wont mess with them, but i will definitly use the lube. thanks.

markho, MB makes a special lubricant for the sunroof mechanism. Recommend using that instead of a generic lubricant.

x2. The MB lubricant is very thin, almost like WD-40 but it sticks rather than runs. Also good to use for window tracks. Lithium grease is much thicker than the MB lube, and WD40 runs off very easily. I don't thinnk its cheap though

I used lithium grease 3+ years ago, and still no problems. I dont think shelling out 20 bucks for a bit of grease is going to help it more.

Try ANY kind of lubricant first to see if that solves the problem

Not saying ti doesn't work and I agree try something before dishing out the cash for MB lubricant. I used lithium grease on my SD's sunroof and it had trouble closing within about 6 months, reapplication helped but it was clear the stuff was too thick as it was very slow and inconsistent along the slide rails. I believe OP has updated sunroof design however, so that design seems to be a little easier on the lube.

grease didnt make a difference. i adjusted screws that push down against the car and point the air dam a bit lower. it worked!!
