Your compressor clutch is not engaged that was why AC is not on. The clutch is controlled by several sensors: coolant temp, refrigerant pressure, compressor speed sensor, evaporator temp sensor... First to make sure your Clutch is working then start tracing back to these other sensors. Look at the compressor, there is a plug of electrical wire on it. One prong is for speed sensor feedback, the others are for power connectors to turn on the clutch. Jump wires to power to clutch to check if it is working. That is just the beginning of AC troubleshooting. Good luck.

My ac is blowing cool air only, it is at full charge

You need to turn off the button that say AC on it. You need to change the temperature and the fan adjustment. If you have the AC button turned on, the fans will blow cool air even though the heat is turned on.

Ac/heat

sounds like a connection at or a bad front blower motor. it's mounted under the hood on the passenger side fire wall. it should have 1 plug going into a rubber like connector. thats your power wire and another going to ground.i think back in 2001 the power wire was purple in color.
good luck chris
