AC Problem

I have a 1997 E420 the cliamte control works fine, how ever the AC will not blow cold air. the machanic has told me that the coolant is not leaking because the system has the correct amount of pressure. Can some one help me out with some suggestions.

I have a 1994 C280 and experienced a similar problem. In the C280 there is a cabinet filter that looks like any air filter. The access is under the dash and high upon the firewall on the pasengers side. I stumbled upon this filter while investigating a blower motor noise. I was shocked that the MB people had not told me about this filter. When it is clogged you get very little cooling. Let me know if this works for you.
