Drove back from NYC last night and almost froze to death. Crazy symptoms: 1. Blower works fine but even with wheel pegged to max heat, there is no warmth to the air flow.
2. Two right side dash vents blow so cold they had to be shut off; two left side blow lukewarm at best 3. Air to floor is icy cold (ambient air?). 4. Problem worsened as time went on. Ideas? I was thinking the problem could be blamed on one of the following: 1. defective mono valve 2. push button ACC malfunction (system not responsive to temp. wheel) 3. defective "AC heater and control valve - used with A/C and heating controls in dash": <http://www.autohausaz.com/secure/PartImages/0008000478.jpg> 0008000478 Genuine Mercedes <http://www.autohausaz.com/html/brandnames.html> - AC & Heater Control Valve; Changeover Valve for Climate Control; 2 Pin & 2 Vacuum Connectors Anyone ever repalced a W123 "AC & Heater Control Valve?" If so, what symptoms did it resolve? Incidentally, the AC blew ICE COLD all summer long. BTW, how do you account for the large price difference in new monovalves offered on ebay that appear to be identical: http://www.ebay.com/sch/i.html?_odkw=mercedes+mono+valve&_from=R40%7CR40&_osacat=0&_from=R40&_trksid=p2045573.m570.l1313.TR0.TRC0.H0.Xmercedes+mono+valve+%2B+%28w123%2C+300d%29&_nkw=mercedes+mono+valve+%2B+%28w123%2C+300d%29&_sacat=0 Thanks in advance, and brrr!
