A/C Mode Switch Diapharm Replacement

["purdueman1970" <townfour@xxxx>]

I have a 1983 Delorean which has a wooshing sound...maybe a vaccuum
leak in the A/C control area....and I am not sure the cooling and 
heating control system is working properly. I want to replace the A/C 
mode Switch Diapharm as a first step in correcting the situation.

I would appreciate some guidance on the proper disassembly sequence 
fo replacing the diapharm...and any other suggestions. This car was 
setting for many years and the A/C does not work...has anyone 
successfully undertaken (long term operation with no componet 
failures) a refridgerant replacement to R134? If so, what did you do?
