I own a E90 2007 320i.
I suddenly lost the illumination from the following:
-my steering wheel buttons
-all the power windows buttons
-the radioCD buttons
-the DTC & central locking buttons
I can confirm that every buttons works properly as before (except of its lighting which makes my life difficult when I am driving during night).
would that be a fuse problem? something else?
or could be a failure of the control element light (switcher) ?
please advice! thanks.
