Better take your Mercedes to the Smithsonian museum. It's the only Mercedes ever to blow TOO cold. Most won't blow cold air at all. You're in an enviable position this time of year!

I'm assuming you've tried adjusting the wheel or what other control you have for the temperature. By chance, are you recirculating the a/c or taking in from the outside? You should get colder air when recirculating but still, setting it for 82 should give you 82 degree air, not 65.

I dunno, but a lot of people would love to have your Mercedes rather than theirs right about now!
