R12 to R134a conversion
#12
Do you have the proper procedure for checking the pressure (Fan in front of car, rpms at 2000, etc.)?
High side should be 2.2 times the ambient temperature in Farenheit.

On a more serious note, one way to get around the evacuation issue is to put maybe one can in, and then let it out, in an attempt to flush the system a bit.

Is it possible that I may be somewhat low on freon without getting a code? I think it should be colder than it is.
Assuming Yes to the above, does the air temperature get noticeably colder occasionally while you're driving, such as after making a sharp turn (especially a left-hand turn)? This could indicate that you're low on Freon. I'm assuming you are, from what you're describing, plus it'* normal to lose the stuff over time (i.e. years) as it can permeate right through the hoses, long-term.
But given the price of Freon, if your system is otherwise in working order, go get the system pressures measured correctly and see how much you really need to add.
