I have a Mazda B2300 and recently my climate control only blows out hot air. I filled the coolant and recharged the refrigerant. Its funny because at normal driving speed it blows cold air when on A/C, but when I accelerate past 30mph it blows out extremely hot air.

So you put one 12 oz can so you could be under charged or over charged aince you dont know how much was in it when you charged it.
