Start with the fan speed turned to its highest setting. They do this for cooling purposes. Turn the air conditioning on while the car is running. Next move the fan setting from the highest to the lowest.

These blower motor resistors get hot. Most ac systems are designed to work within a large range of temperature variants and environments however due to numerous causes the air conditioner is still prone to overheating.

Low coolant level counterintuitively the same system that keeps your engine cool is responsible for the heater working.
