What can Toyota air conditioner do if the warm air is not hot?
1, heater water tank blocked
Hot inlet pipe of warm air water tank and low outlet pipe temperature are all symptoms of poor circulation of air conditioning water tank. The radiator of the air-conditioning water tank is very thin. After long-term use, the scale and impurities in the coolant will block the pipeline of the radiator of the air-conditioning water tank, resulting in poor circulation of the water tank and unable to provide enough heat to convey warm air to the cab. This situation belongs to the internal blockage of the air conditioning water tank.
However, if the heat sink outside the air-conditioning water tank is blocked, the airflow generated by the air-conditioning motor will be blocked by the heat sink of the air-conditioning water tank and cannot reach the cab through the air-conditioning outlet, resulting in poor air-conditioning heating.
Suggestion: Check the heater water tank to see if it is blocked. If yes, replace the heater water tank.
2, air conditioning filter plug
The main function of air conditioning filter element is to filter out impurities in the air entering the air conditioning system. If the air conditioning filter element is blocked and the air entering the air conditioning system is insufficient, the air conditioning fan cannot generate enough air volume to provide warm air for the vehicle.
Suggestion: Just clean or replace it.
3, air conditioning motor aging
When the motor of the air conditioner is aging and the working efficiency is reduced, there will be a situation that the noise is high but the generated air volume is small, and the heat of the warm air box cannot be transferred to the cab in time and effectively, resulting in the situation that the warm air of the air conditioner is not hot. In addition, the blockage of air conditioning pipes is also one of the reasons for the small air volume of warm air.
Suggestion: Go to the 4S shop to replace new parts.
