[Shop-talk] trucks a/c

[gordies garage]

You may be SOL Tim.  Having been in the retail car business during the 
switchover from R12 to R134a, I remember well the complaints of the AC 
not getting cold enough.

Because I can't handle the heat, I had to basically get the a/c system rebuilt/replaced a few years ago. After being taken to the cleaners by the first shop, I have now had it looked at by a shop where we know each other and I trust them. A couple days ago I was told the system is charged, pressurized and not leaking. And it was cooling down to 68 degrees; not too bad a temp but when the truck was "younger", the a/c used to get so cold as to almost be painful (I say almost as I love the cold and where shorts year 'round here in southern WI).

(The guy at the shop basically said there was nothing else they can do and didn't charge me for the check up; which is a nice thing.) I plan on cleaning out around and in between the two radiators this weekend. Hopefully this will help.
