Hello to Fitz and all my 780 buddies.

Do you think we could get a seperate 780 forum?

Here is some info about removing the rear inside panel to gain access to the window. If yours has never been apart it is quite possible to break something. Treat it gently; these peices dry out over time and become brittle. The back seat has to come out first. Some that haven't been out before seem like they are welded in.
Then the insert has to be gently pried out of the handle and the two screws removed. There is a screw where the panel attaches to the floor under the seat, a screw under the little cap on the door threshold and an allen or torx screw just toward the rear from that one. Then you can pop the panel off - GENTLY - because all that should be left are the pop in retaining clips. Some ot those will probably stay with the car. There are a lot of them.

Once you get the panel off, the rust should be evident - if you have it. There is a peice with three screws in it that runs across under the window. If it is real rusty, you should probably pull the window. To do that, you will have to pull the rear shelf and the trim panels around the window. I cannot help you on this because my body man did it - and even he broke a peice. After you remove the trim around the window there are about 12 screws that screw into the window frame all around. Remove them and you should be able to pull the window out. After you get it out you will see the holes to the drain system. Blow some air throught these to clean them out.

If you are not really skilled in this area and/or do not have a lot of patience, you might consider taking it to a good body shop. But at least you can pull the interior panel and see if the probelm exists. Then make a decision from there.

I hope this is some help and even more so - that God has blessed you with no rust! Contact me if you need other advice - or moral support. I am going away with my wife from the 26th to 31st so if you are working on it then, I will not be answering. I'll get back to you the first of the year.

I wish for you all a safe and merry Christmas!

Blessings!
