E70 Drivers side mirror bad after water ingress
The drivers window got left down in a rain storm. The window switches quit working and I replaced the switch panel. Then the mirrors started acting weird, opened and closed a couple of times uncommanded. Finally the drivers mirror won't respond at all. I'm getting an error code referencing a LIN communication failure with the mirror (9CBA I think). I can clear the code and the windows start working but the mirror won't . Eventually the code comes back and the window switches stop again.
All fuses check ok.
I'm off troubleshooting. I'll let you know what I come up with.
