To add to the above answer......
If your AC/Heater was working fine but all of a sudden quit working, there is no need for a complete AC system purging and recharging. Buy the Climate Control Module 09352675 and install it yourself. It take about 20 minutes. Another note here: This module also controls the rear window defogger. If the module is truly bad, none of the lights will come on, controls do not work and the rear window defogger will not work.

This process can help reset the climate control system and restore proper function.
You can try doing a battery reset by disconnecting both terminals and touching them for a few seconds and reconnecting, if this does not work you will need a scan tool to read and reset the codes set in the system. the proper scan tool will also calibrate the blend door motors.

With the engine on turn off the climate control. Make sure you push the "off" button twice to turn completely off. Also make sure the radio is off. Close all doors then disconect the battery at the negative terminal. Wait about 20 min. Reconnect battery then start motor. Start climate controle and let it do its recaliberation while the engine runs. Should take about 5 min.
