Larry;

Thanks for the discussion as I was hoping that you would bite. Been listening to your responses and your assistance to others. I am located in Maryland and it has been in the 100's for the past several days.

Do you believe that any regular A/C shop will be able to do the things that you mention if I were to bring your reply to them? The only thing that I was told by the previous owner, a friend of mine, is that his mechanic was looking out for a used part as the repair was to be expensive if they tried to find new. I gather that it may mean that it is the evaporator but I am not certain. I will be trying to contact the previous mnechanic and find the name of the suspected part.

Again, thanks for the assistance as it is most helpful.....Marc
