Moisture inside windshield

[haromaster87]

Hey guys,

This might just me being paranoid, but after I had to get rid of my W116 because of rust, I want to make sure my W123 stays rust free. The guy I bought it from gave me a bunch of receipts to work he had done on it, and among those was a reputable place that replaced the front and rear windshield seals. The new seals look great, and they look to fit quite well and solid. However, there's a couple of things that concern me about them. And I remember on the 116's, it was very hard to get new seals to really seal properly. I don't know it's the same for the 123, but I'd like to check.

First- The front seals look great, I can't visually seal any problem areas. However, after the car sat in a very long rain, and then in the Fl humidity, I got in and found there was moisture on the inside of the windshield. Not to the point were it could bead up and drip, more like a mist, that I just wiped away with a towel. Does this indicate a possible leak in the front windshield, or is it possibly just some humidity inside the car?

And the back windshield, this seal also looks good, however, I noticed that the rubber trim that sits between the glass, and the chrome trim, has a small gap. It's two spots that are no more then a few inches long, and it's like a gap between the rubber and the chrome trim. I would imagine it wouldn't be hard to fix, but I worry about the water that's been there already. Does that sound like an area of concern? If so, were would the water have drained to?

Thanks for any help guys, like I said, I just don't wanna miss a rust causing issue.

Doesn't sound serious if it occurred after heavy rain and in FL humidity, and as you say, was just misting not actual drips down glass.

Assuming your car has a sunroof, have those seals been done as well?

If it was heavy driving rain, even a bad door seal could contribute to that sort of moisture on the inside.

Here in the pacific northwest I've seen that on a lot of rigs in the winter and spring. The air is VERY moist, and when the sun comes out and heats up the inside of the car you get condensation on the inside of the windows. Next time it's going to rain try cracking the window ever to slightly to allow moisture to escape rather than condense. See if that helps. I'm guessing it's just condensation.

Usually when the winshield seals leak you end up with puddle on the floor because the water runs down the front and seeps in at the bottom. Though in my 240 when driving in the rain I was actually getting water driven between the top of the glass and the seal. It would then run down the inside of the windshield.

123's are notorious for getting rust in the spring pockets, and under the battery tray... inspect the areas heavy!

The rear window may have a small shelf-like edge that lets water sit on top of the rubber and lean/seep toward the glass. It may/may not leak under the hat shelf or into the trunk. After heavy rains, you may want to check the rear corners of the trunk to see if water trickles down the fenders and then into the trunk.

Also check your trunk rubber seals.
