What belt drives the heater in an 1999 Mazda protege?

In a 1999 Mazda Protege, the heater is driven by the engine's serpentine belt. This belt powers various accessories, including the water pump, which circulates coolant through the heater core, allowing the heater to function. If the serpentine belt is damaged or worn, it can affect the heater's performance. Regular maintenance of the belt is essential for proper heating system operation.
