Is is blowing hot air on the drivers side, or nothing at all? If it is blowing hot air even though you have the thermostat set on cold - it could be the heat actuator. It will occasionally do this after about 75000 miles or so. Mine started at 114000 miles and if you turn it off and turn it back on - it will start blowing cold again...$400 repair. Hope this helps.
