AIR CONDITIONER NOT WORKING PROPERLY
 

I have a 1996 C280 with 156000 miles. My A/C was working fine about a week ago. Today I turned it on it only blows cool air. I check the compressor and it seems to be working fine because the clutch is angage as a good sign that there is enough freon in the system probably no leak. I am thinking that the indash climate control switch is the guilty party there. Does anyone have any idea on what is going or have any experience with that kind of problem. Any help will be greatly apreciated
