First, check to see if the AC compressor is cycling. If it doesn't, check the freon level. If it is too low, it won't work. If good, you need to check if the compressor is getting power. If it isn't check the cycle switch.
If it is working, check the blend door in the vehicle that is located near the heater core. If it is stuck, you won't get cool air, but rather, you'll get heat.
