The Defroster-A/C system on my 1997 E320 was acting up. It was behaving erratically. It would only operate at full on or completely off. The dealer said that the motor control system needed replacement, but that in order to do this the whole blower system had to be replaced. I guess this is because of the way Mercedes packaged the setup. Result was a painful US$1100.00 bill. Is this reasonable?
Anybody else experienced this problem?
