i would highly recommend doing some more research on recharging the AC systems . .depending on what year your car is they ended up switching the freon .. r12 to r34 or somethign like that (2 different chemical make ups) .. and they CANNOT be mixed . . i dont know what year they switched .. maybe 94? but anyway - you cannot buy the old stuff anymore because it eats holes in the ozone - only option would be to switch out the entire system to the new system . .

(i havent had time to research this myself and i gotta run to work but before you try anything try to verify this all first)
