I just noticed that the rigid plastic part underneath my windshield
wiper arms is breaking away in chunks on the edge that borders the
windshield. I can see some leaves and other debris in the space under
it. Does this piece seal anything, or is it just a trim piece. I
haven't noticed any leakage, but my wife, who works in another state
where it rains all the time, has a 92 that frequently has fog on the
inside of the glass. She said hers is cracked really badly. Even if it
is just a trim piece, I might replace them if it's not too big of a
job. Has anyone replaced one of these who could give me any
Dont be surprised if you happen to find a lot of rust underneath too. A
'93 325i I had started to get really bad around the bottom of the
windshield, and I would have never known if I didn't need to change that

Interior fogging of windows can be an indication of a leaking heater
core (pinhole leak). Keep watch on the coolant level to see if it is
dropping. If the windows appear to smear when trying to clean the
glass that is a good indication of ethylene glycol being deposited on
the window glass. You might also get a slight sweet smell in the
cabin. Lets hope that isn't the case.
It's a trim piece, it is not a seal.
Your wife needs to run the AC to clear the fog from the inside of the car.
Fog on the inside is a result of relatively warm, moist air in contact with
the glass -- sort of like the way a beer can collects drops on the sides
when you take it out of the 'fridge. I understand that she may want the air
to be warm, but she needs it to be dry. The AC is a dryer, so turn the AC on
and set the temp controls for the warm condition she likes.
I replaced this part on my E36 and on my daughter's E46, I recall the cost
to be in the range of about $60 at the BMW dealership.
Thanks everyone. My wife does indeed have to run the A/C even when it
is cold outside to clear the windows. Every fall the low coolant
warning appears when the temperature starts to fall, so she may have a
bit of a leak. She's in snow country, though, and the snow from her
boots and clothes gets in the car, so when it sits in the sun there is
plenty of moisture all winter long from the melting snow and that's
mostly when the windows fog. I think I'm going to replace the pieces
just to keep the cars looking good. My 94 is looking really good
otherwise, and hers is practically like new. I ordered some Boston
green paint in a spray can online (along with some clearcoat) and
fixed up some flaws in the paint, and then put new pinstripes over the
old worn ones, and after polishing the thing until my arm almost fell
off, the 94 does, too. The only other thing that plagues both cars is
the rubber strip above the rear window, so I guess that will have to
be done also.
