oso they do have them cuz i dont want to have it filled when its already full. ill ask my dad to see if he has his ac tool and ill call a few car guy friends.

The temp at the vents should be at least 20 degrees F below ambient temp[outside temp]...it takes 2.0 lbs of 134a....may be low due to leaking compressor seal.....ask me how i know....

hmm. last time I tested the temperature of my AC system on max the air coming out of the vents was 42*. :?

Yes, you are exactly right. The difference in temperature should only be about 20 degrees. Air conditioning was never designed to keep a home or car like a meat locker! That'* what we leave coolers and refrigerant for!

You should put a set of guages on that car to see what your true pressures are. Simply adding freon to a system that seems "warm" can be very dangerous if you just "put in more freon." Over charging is more dangerous than not having enough freon because the system can rupture, causing more damage, or injuring yourself.

As a side note, do you hear a clicking noise when you turn on the air conditioning? If so, does it click on and off when the car is idling? That is usually a sign that the system is low on freon (the compressor will cycle on and off to protect itself from seizing due to low freon).

Dano didn't look for a leak before pumping close to 2 pounds of freon into my car. But it took almost 2 pounds...

nothing is leaking and no clicking sounds maybe i just got to get it blow harder cuz i also asked the dealer about that too and they said it was cuz it was electronic and they dont blow as hard as the non electronic.

Horsepuky.... My dads Ledabre (Electronic) blows harder then my Bonne(non-E)...

Hello,
I have 160K on my Bonneville and just converted to 134a and i got it as cold as 32 degrees, Thats nice and cold. This is without the vaccume.

huh? I thought most cars click when it AC is on and you are idling.

If you have no freon also you will not hear it cycle at all because its been prog'd into the computer so if you do charge it you have to reset the computer by unplugging your bat. so it cycles the new freon in.
