AC Problem on 1995 Chevrolet 1500 Pickup

My truck is at 48K miles now and the AC is no longer blowing cold air, hot air only off the engine. Is this an electronic problem or does the AC system just need recharging?

Another ? I have is did it stop blowing cold all of a sudden or gradually.

The first thing to check Brenden is the A/C system pressure. This will tell you if the system is low or empty. Good Luck!
