My 99 320E had its original battery fail and every thing went crazy. I could start the car and drive but the Alarm could not turn off. No window controls, no seats,no keyless entry, weak wipers and slow turn signals.. A new battery has miraculously cured most of the quirks. However so far the four console window switches wont work ,power mirrors also out. However the windows can be raised and lowered with the remote key. Fuses appear ok. will see if mirror moves like it used to in reverse.
I searched this several ways for the past hour but it sounds like this all goes through some central computer. Will it reset itself or could the low voltage damage a control module. The four switches would not all go out at once!
