On this 1995 E320 Wagon I inspected the A/C air filters. I had to pull back the lower seal of the windshield and noticed that someone had been there before: The black, hard plastic extrusion glued to the bottom edge of the windshield glass, the one that holds the rubber lower seal, is severely damaged. If I don't replace it, the seal won't stay in place. I have removed the wiper assembly. What is the P/N for that strip and the procedure for replacing it? What adhesive to use?

Today I visited my friendly Mercedes dealer. He had a windshield in stock an let me look at it. The plastic extrusion I'm refering to comes with the window glass. There is a nylon spline (a 1/8 inch diameter rod) inserted to prevent the installer from damaging the plastic extrusion. Obviously, what happened on my car is that someone damaged this plastic extrusion and it appears that I must replace the windshield. I'm not entirely happy. I hate it when people work on my car and break things.

My lower seal was flapping in the wind also, as the rubber wouldn't stay into the plastic. I simply cleaned the rubber, and windshield, and used some 3M double faced tape to make that tight seal again. Seems to be working good so far.

Thank you, Pete, for your reply. I think it's critical to have the rubber seal tight against the windshield. Otherwise, water leaks into places where it causes damage. What number 3M product did you use and how wide a strip? I understand that the molding is EPDM and requires butyl based tape. When did you do your repair and how well does it hold up?

I used the 1/2 inch 3M double faced,,, I believe there is only one kind,,, and it has been holding up well so far. As far as keeping water out, I don't really think it is that critical, in making a watertite seal. I could be wrong, but my wagon has been loose for a couple of years before I decided to fix it and I know there are no issues related to water in the front section of the car. God knows I have had it torn apart enough times to see.

They all get like that..I use a thin bead of clear silicone chalk,just below the rubber line [ where it meets the winshield-you do not see it once assembled] It will peel off if you have to do the filters again.
If the channel is not broken, you take a thin blade and clear the slot out so that the rubber lip will go into the channel.. it will not snap in there if the channel is not clean/clear.
It is not that important..check the corner drains I put the garden hose right down in them while I have it apart.

On my 87 W124 230e I had loose rubber caused by incorrectly reinstalled plastic trim. Water ran under it, down the windscreen, missed the water run-off channel at the base of the windscreen and wet the fuse and relay boxes. Bad place for moisture, I'm sure it caused an occasional stall at low revs on very rainy days. I got silicone sealant. But first I removed the trim and rubber, cleaned dirt and gunk off windscreen and rubber with turpentine, slotted rubber on to plastic trim, then refitted, this time snapping the plastic trim firmly into the 3 retaining clips. Tight as a drum now, no need for any sealant.
