Leaky C123 280CE 1983
I wonder if anybody out there has experience of sorting out the water leaks in a C123 coupe?
I've recently bought a beautiful Hansa Blue coupe from 1983 and am slowly going through it, sorting annoying little faults.
But where I've drawn a blank is resolving it's rainwater leaks into the car. If I lift up the left and rear passenger mat (with water-absorbing sponge backing!), there is always a puddle.
The door seals are in reasonable shape (not perfect) but there are definitely issues with the rear windows. For one thing, when the windows are closed you can actually see a little gap in the bottom rear corner because the window has traveled a little too far, then cocked itself forward at the top, just enough to reveal an air gap.
Although it turned into a much bigger event than I had hoped (rear seat base and back had to come out first), I removed the panels covering the Rear (electric) window on the left side and tried to figure out why the window was traveling too far and cocking over a bit but all I could really see was that there are two rectangular teflon blocks that guide the window up and they appear to be worn (I'm going to have to try and track some new ones down). Apart from that, the seals [I]seem[I] to be ok although I imagine I'm going to have to end up replacing them...
The horizontal upper seals that the front windows rise up and press into are kind of perished so I'll have to source those too (so far no luck- any ideas?) but when you study the seals you realise they go on forever, all around the inside of the door opening and they look like a nightmare to change!
Anyway, on the day I had the rear window interior panels off, I had dried up the floor puddle and it conveniently started to rain but NOTHING was coming in via the window but sure enough the floor puddle started to exist again but for the life of me I couldn't identify where it was coming from.
I'm willing to bet that just about every coupe of this era must leak as the whole system is so so complicated and chock full of possible problems!
So, there must be somebody out there who has tackled one of these- can you help me please?
Also, if anybody can point me in the direction of a somebody who sells all these seals (preferably in Europe as import duties from the States are very high here in Italy)? I know they are going to cost me a small fortune but it's got to be done!
Thanks in advance
BTW I used to work as an engineer in the Mercedes engine plant in Marienfelde, West Berlin in the early 80's when this car was built!
