W212 Lin bus 1 communication error

[Ferrari7288]

Hi, my air condition has stopped working since February and I’ve changed few of the sensors that I know (Air quality, humidity and temperature), however there was no change. I get the error “D00800 says LIN bus 1 has a malfunction.” And I took it to a Mercedes specialist and they told me there’s an internal electric fault and I have to take everything apart just to make sure the wiring is okay . If anyone has got a map of where or how the lin bus connects together that would be really appreciated!

Also the windshield was changed by the previous owner which is probably why the the temperature sensor on the wind shield shows -40*
