Mercedes Benz repair: AC Blower does not work on high status, number search results, cabin filter

Question
Hello, my AC is no longer has high/max feature. It only reaches medium air flow.  I recently went to a garage and I was advised it was my air modulator (only a switch) and that it would cost $900.. Is this true? I have a 1997 E320.. This car has been maintained perfectly but I can't understand why this much for a switch/fuse..Please help.
Sincerel,

Rick

If you have not replaced all of the ACC Cabin Filters, this could be your major issue.
When they begin to grow mold, the blower speed drops drastically.
