Earlier this year I found a large puddle of water on the floor on the drivers side of Inga, my 1990 740GLE.
Eventually I found the source of the problem, it was a leak where the sealed up manual air vent comes through the side panel next to firewall in the drivers side foot well. The O-ring around the plastic fitting sealing the vent was worn and I couldn't get another one. I sealed up the plastic fitting into the sidewall using silicone.
Today I found a similar puddle on the passenger's side - arggg not again!
So I removed all the carpet and underlay after removing the passenger seat. With the help of my good wife using a garden hose in the problem area, I tested to see if the same problem had arisen. No leaks. Further investigation revealed that water was coming trough the door. WTF.
So while the carpet and underlay is drying out I proceeded to remove the door trim. Fortunately I had a Haynes manual to follow. It turned out that the small water deflector had fallen down into the door. It's the one that goes behind the door speaker. So instead of water being deflected to the outside skin and vented that way it was dripping down the door trim and into the car.
OK. Now that I have it all apart letting it dry out is there any servicing i should do on the window mechanism before I put it all back together? By the way it an electric window.
I should also mention that I will be installing additional soundproofing before putting the carpet back in. I have both additional underlay and some Dynamat left over from when I did the drivers side months ago.
