02 was the crossover year for the Explorer plenum box, so it's hard to guess which one you have. However, the most common failure on both the old and newer system is problems with the air flow controlled by the blend door.
If the problem is a dead fan motor, check the fuses and motor wiring. If it's lack of heat, the problem is likely the blend door. Check HeaterTreater.net for diagnostic procedures and fixes for both models.
