if its completely empty should take about 3 pounds
if the a/c is empty it can hold 1.9 to 2.1 pounds of freon

The 1996 Nissan Maxima air conditioning system has a capacity of 5.4 pounds of Freon. A recharge kit will come with a gauge that will tell you when the system is full.

You take it to a professional, the freon you buy in the store is not what your car needs !
1.6 pounds
Buy a kit at auto parts or Wal-Mart comes with instructions
my guess is 2 pounds
Freon is too low, or too high.
you can let some freon out. you could have to much which will not let the compressor work. ihad your problem,and that fixed mine.
you can use a 1989 thru 1992 ac compressor in 1993 they went to 134a freon so they ar different.
