2005 Mercedes S600 W220 AC Blows Hot Unless its Set to Low

This Video is for reference only, do this at your own risk. It may not be the best way but it worked for me. Thanks to BenzWorld for great info.

Symptom: Ac blows cold only when set to low, any other temp setting it blows hot in manual and in auto modes. All Zones are same no change. NR 01 is the value for "in car tempreture". When that value is 0.0 sensor is probably not working, unless its that cold in the car lol then u probably dont need AC :). This will work with E-Class, S-Class, SL-Class or any W220 Body Style, according to the BenzWorld.
Good Luck
I just wish i knew about it a year ago(I lived with this problem for a year, michanics and dealers said its normal for it to work like that, I guess they are "sometimes" wrong Lol)
