The heater flap is in the air conditioning module, so it is difficult for the owner to disassemble the flap to warm the heater. A more appropriate method is to go to the 4S shop or the outside repair shop and inform the maintenance personnel of the vehicle problem so that they can disassemble and repair it.
Generally sagitar warm air is not hot for the following reasons:
1, the hot and cold flap was not closed tightly, which caused cold air and warm air to enter the car together, giving the passengers a feeling of being half cold and half hot.
2. It may be that the internal heat dissipation management of the warm air water tank is blocked, which reduces the speed of the coolant flowing through it, resulting in insufficient heat, which leads to the warm air entering the car being not hot.
It is also possible that the thermostat is broken. If it is not closed, the ambient temperature of coolant will be low during circulation, and it will not be hot if the water temperature is not warm enough.
