I went through your A/C Troubleshooting. Now what? Everything in your list checks out a-ok. The compressor is running. The system is pressurized. There isn't any leakage anywhere. The door is opening and closing as they should when switching from warm to cold. But my car blows hot air and it's over 100 degrees right now where I live. I am on a very limited and fixed income. There is no guarantee that I can afford to have have it fixed. So what do I check now?

Could be freezing up due to air and mositure forming ice and blocking off the orifice tube, also the air blend door could be stuck in the heat position

Like I said, the door isn't stuck in the position to where it would only blow hot air. The belt is fine, the clutch is engaged, there isn't any refrigerant leaks, and it is pressurized, the fuses are good and had been changed anyway, and the vents inside are opening and closing. I seriously doubt there is a build up of ice blocking the tubes because the temperature would be a little cool in the beginning at least. Meaning that it would start off cool and then go hot but it doesn't. It's just hot air. I just bought this car in October and the A/C didn't work when I bought it but I thought it would be just a recharge issue. When I found that it was fully charged I started going from one thing to another to find the issue. So I have been working on this for 9 months now.
