I Need Help With AC Problem?

-I just did my first ac charge. My only question is why is my vent temp only 65F when it is 90F outside. I've read that it should be at 40F. The system was completely empty and I put in 8oz of Retrofit Oil and 24oz of R134a but couldn't get the cans to fully empty so I guess I only have about 20oz the car calls for 34oz of R12. Could that be what my problem is? I didn't pull a vacuum on system. Should I go ahead and buy another can of R134a.



Oh yea the sight glass has a couple of big bubbles moving around, should their be any bubbles.well two things, one you should have drawn the system down to get all the moisture out and air,thats why it isnt loading all the refridgerant, and now you have to do it over again or live with it, that air and moisture is taking up room where the refridgerant goes, OH MY!, . second an r12 system on an older car dosent usually cool as well with 134 in it, it wasnt designed for it and the evap core isnt as big on a newer models i beileive it is,or condenser anyways, and you might have to install and aux electric fan to move enough air acroos to make it lower the temp more, i went to a junk yard and fouind one off another car and hooked it to the ac switch to turn on when i turned n the ac, ,you probably dont have a draw down unit and its hard to do without it, if its blowing cool your doing good, for the mistakes you made, not being smart , that moisture in there will freeze up and slow the system down, from cooling, call a rental palce and see if you can rent one, if you lived in tampa id let you come over and use mine,
