I just bought a 2000 540iT w/90K miles.
My (non-dealer) mechanic cannot locate the source of an electrical
problem regarding the AC and the self-leveling suspension...
All AC controls function, but power is not getting to the compressor;
he can force the compressor to function by energizing directly,
apparently the same with the suspension function.
There is an on-dash error message regarding the suspension, but
not the AC.
Any suggestions (besides taking it to a dealer)?
Thanks in advance,
Fred in South Carolina
