Hi. I've been a member for about a year and have enjoyed the helpful advice. I have a 1970 sedan Deville and recently had the ac recharged. The compressor is working and I know that it is cooling...

Sometimes it blows cold air as low as 55 degrees and other times I cant get it below 70. If I move the climate control to ice then back to high sometimes it blows cold again and sometimes not. This leads me to believe that there is a problem with some vacuum actuator/baffle that isnt opening or closing.

Before I start tearing into stuff, some advice midget be helpful. A diagram would probably be nice also.

Thanks in advance for the help.

Joey

Ok...I found this diagram. How can I check to see whether the temp. door and purge door are operating properly? When the heat blows, it is hot fast. Is there an easy way to do this?
