I have a 2003 gsr and my ac does not blow cold at all. The eye for the ac lines that suppose to have a green dot is black which means its low on refrigerant. Has anyone recharged the AC on the evo? Know how much refrigerant our cars use or which side is high side and which side is low side?

 

Go to Advance auto and get the low pressure charge bottle maybe too of them. Whichever nozzle it fits on thats the low pressure. You wanna have the A/C on when you do this or its no point. Connect the bottle and fill till the light turns green OR till you get enough pressure. Most of the bottles have a gauge to tell you.

 

Sounds a bit soon to be just a recharge needed. I am betting you have a small leak somewhere. Get the the stuff with the die in it so you can see if it leaking when you put it in.
