Answers :

Just a little low on freon can make it get too cold and it freezs if you in position to check the freon level you'll find with the system on high and the engine reved up the low pressure is below 25PSI. fill it to reved up is above 25 and your problem will go away. Low on freon will make it cold enough to frezze up and then warm up as the air does'nt go though the ice. it'll work good as you start up till it frezzes and after it's stopped up with ice it blows warm (it's really too cold). the more freon in the system the warmer it'll all blow because all the pressures are higher and it's the difference in pressures that make it cold.
