[DML] Re: 47 Degrees with the AC knob in the normal position

Geez you are grumpy.

I'm not trying to prove anything -- just keeping a tally of owners with ice cold A/C who did nothing more than flush the system, vacuum it down, then recharge with R134.

Poor Farrar listened to the "tear it all apart" crowd, and look where he is now....

Tearing into the system and replacing components is an *OPTION*, but it is not necessary (component health permitting). Speaking for myself, I have only replaced two components on my own system: the low pressure switch and the compressor itself. Everything else is original to the car, and everything else works great.

And I did flush my system, thank you very much. In fact I have flushed my system several times over the years. As I told Steve earlier tonight, after this summer's A/C season is over I plan to do it again as a preventative measure. The lower probability I will ever need to mess with my orifice tube, the better. $13 of freon (and a little paint thinner) is cheap insurance.
