Thread: Windshield rubber gasket at base of 94-95 models

    Windshield rubber gasket at base of 94-95 models

    I am not sure if it is applicable to 500, so, posting to 400 section.

    Anyone seen an issue with windshield gasket over time where they pop out of the channel (or groove) that's built into the windshield? I wonder how common is this and if I should consider replacing it? I took everything off and cleaning the channels really well, so, dirt/gunk is not an issue.

    Thx

    Re: Windshield gasket

    Do you mean the rubber weatherstrip along the bottom of the windshield? If so, what year is your car?

    Edit: See post #3, thread title updated.

    Yes, that's correct. 1995 E420 with one piece gasket that is integrated into the wiper assembly. I am assuming facelifted 500s had the same design.

    They do and the proper windscreen has a channel on the glass to grab the seal.

    That's what I am referring to. I cleaned the channel really well and got rid of all dirt and gunk. Yet, the gasket won't stay put for long. It will seat properly and after a day or two, seems to pop back out. Hence, my question if it is a common occurrence. The options are to either 1) try a new gasket (and deal with removing over-engineered mono-wiper and break some brittle plastic parts) or 2) a putty type material that does not harden with time and is easy to remove when I need to replace cabinet filters.

    Re: Windshield gasket

    Sadly that gasket seems to have a memory as it bakes in the sun and natural elements. If it were me (I am a bit anal about the E500) I would replace the gasket with new rubber, cleaning and lubricating the complete wiper system in the process. I think you can try to come up with some sort of fix and report back. It is an issue for many having a strips being like bacon rather than fitting nicely in the channel.

    The PO of my car replaced the windscreen at some point using 92-93 glass example, so I am a somewhat sloppy look.

    Re: Windshield gasket

    IME, the plastic channel at the base of the windshield tends to have areas that crack or break, or possible spread so the channel is wider than normal. Problem is, the channel is not sold separately and only comes with new windshield glass. Used ones may have similar issues unless they are not very old. I believe this design was used on all facelift (94-95 USA model year) 124's and also some very late build pre-facelift (93 USA model years).

    The problem with the replacement rubber gasket is that it's not easy to replace; there is a fancy metal clamp that attaches it to the wiper mech. And, I'm not positive that a new gasket would solve your problem, it may still not "stick" in the old channel.

    I would vote for servicing the HVAC blower motor (remove to check brushes, lube bushings/bearings with ATF, re-install), replace the filters, and then use some sort of goop / putty / adhesive to 'glue' the weatherstrip down. As you mentioned, avoid using anything that's too permanent as you'll eventually need to remove it again.

    mikeym: I had this problem with my 94 E320. In my case rain water drained behind the weather stripping hitting the OVP relay and shorting it out over time. Car would not start. Replaced several relays until I figured out how water was getting in there.
    In any event now that you've cleaned the channel make up a solution of dish washing soap and water and liberally spray the channel and weather stripping and re-insert once more. Use a plastic trim tool to push the weather stripping into the channel. If it won't stay due to years of exposure then replace it. Note: the metal band clamp that fits around the wiper head is one time use and is NLA. You can use glue but the new weather stripping fit so tight on my car I didn't bother. Also I had to trim each end of the new piece so it would fit at the A pillars.

    Regards,

    folks - thanks for all the suggestions. I am going to try Peter's idea of soap and water to see if I can get better seating.
    I really hate the design of this gasket especially with wiper integration and using one time metal clips that are NLA... will report back with updates in few days.

    A penny sized dab of SIKAFLEX will hold this in place and still be removable later. On the pre facelift models the tab on the trim loses it's rubber/vinyl coating and won't set into clip.

    KJ in Oz.

    Following suggestion from geraniumtr, I took another attempt at cleaning the channel and the gasket and then used soap solution to push the gasket into the channel with a putty knife. Seems to be holding up for now.
    Don't want to take a risk with the start of raining season and will likely use SIKAFLEX to hold gasket in place.

    Just curious, which specific Sikaflex product is recommended here? There are literally dozens of different products with the Sikaflex brand name:

    Hello my name is Per-Christian , from Norway. An E500E enthusiast for sure , but I haven`t got my hands on one yet. I do have a 260e -92 and an E320 -94. The E320 does have the same issue with this broken plastic channel below the windshield. I did have it hard to believe that this plastic channel is only possible to get with a new windshield.(I guess it does come on a new genuine mb windshield if you order one) But it`s ridiculous to have a new windshield only to get this plastic,- especially if your windshield is pretty good. I did some research on the www. Luckily I got the answer I wanted. Now I have the new separate plastic channel ready for install. My local windshield repair shop could easy get it. This is not a genuine mercedes-benz part as we can`t find it in EPC. Probably Pilkington or someone else who`s the producer.

    If you search for 5328ASGSB you will find some information.
