bmw e60, 2005 , power window not working,need full body gateway module diagram

hello guys.
i want to say a funny story about idiot mechanic and dealership , with almost complete exploration of bmw e60 power window system. while i need some help also.
i have a bmw e60 2005 ( older model befor 2005 has door module, this one has not and body gateway module do most of activities) which it windows stopd working after washing the hole interior. when i got this car a stuped mechanic already changed window fuse , and i think with higher amper fuse while it was still wet. owner say it was smell burning coming from back of glove box for 2 week after changing the fuse there.
after that bmw dealer diagnostic the car and they got 1300 $ to find out the problem. they believe problem was driver switch block.
- the car came with me with a second hand switch block and surely after a quick i recognise thats not the problem.
there are 4 wire in switch block
1 . red , yellow 12 v
2. brown 0 v
3. i cant remember the colure but 0.08 v
4. blue with white strip" fix" 0.12 v engine on or off ( which suppose to be "can line " and connection between body gateway module and switch block. there is no short circuit or open in non of the wires, i am wondering what module create this can ? is it inside of body gateway module? or i comes from another module?

*some wiring and schematic attached. for who ever likes to have it.
**Extra information about this car power window conditions .

-i opened the body gateway module and there was no evidence of such a burning at all.
- all of windows worked perfect with remote key. but after changing new switch block driver side window close dont work ( also checked with diagnose tool. but surly still working with putting battery voltage on it.
-just passenger window key operating normal.
- driver switch illuminate but dont work at all also mirrors and back windows are not working either from their switch or driver sw.
- diagnostic tool has no reading on the when i push the the driver switch buttons.

more attached i founded for you information.

some of them are not for the same design which i questioned.

does this support bi directional controls with a scantool?? also can you see data in the module seeing if it sees you pressing the switches?? i have no experience with bmw's but on the newer gms you can do all that with a scanner

thats is true.
also in good manifactured german companies like mercedes , bmw or vw also it is possible to do bidirectional test. and it helped me to be sure my wiring from body gateway module to window is ok, and also my wirings.
but when i press the window bottuns while i looking at my data streem , tbere is no reflection
