The heater resistor has probably gone out. It should be located in the blower housing.

It is located on the right rear of the engine compartment. held in by two screws.

Check the blower motor relay, usually located under the hood in a box, also check the fuse in the fuse panel for the blower motor. If both of those are good then you have a bad blower motor.

Under the dash panel in the heater box on the passenger's side next to the blower motor, it's held in by 2 screws.

The air door is a flap / door that opens and closes to control the air flow for the haeter and air conditioner its usely on the heater box where the heater core is locatedon the top of the heater case unforanatly you need to take half the dash board apart to get to it. And i have the factory manual for this vehicle and it dosen' t realy tell you how to do this if you want i can fax it to you but itsnot easy and thats why they leave it so incomplete its a poor disign and they know it so they don't say
