What if the car heating is not hot? Check the maintenance method (graphic)

What if the car heating is not hot in winter? Here is a brief introduction to the inspection and maintenance methods of automobile heating. You can check and eliminate the heating fault of the car according to the steps.

Check whether the hot and cold air switch is good or bad.

Check whether the hot and cold air changeover switch is in the red position. Red represents hot air. If it cannot be turned to the red position, further check whether the switch is faulty or the heater assembly is faulty.

Check the blower switch.

The heat of most cars is provided by the cooling system, and no additional electrical equipment is needed. Blower switch is the only electrical equipment to control heating. If the switch fails and the blower cannot be turned on, there will be no heating in the car.

Check whether the thermostat is good or bad.

If the car doesn't have a thermostat or is always on, the water temperature of the car won't come up, and the owner won't have heating when he turns on the warm air. In this case, you can only go to the repair shop for maintenance.

Check whether the heater core water pipe is blocked.

If the water pipe of the heater core is blocked and the hot water cannot circulate normally, there will be no heater failure. You can judge whether the water pipes are blocked by feeling whether there is heat in the two pipes with your hands.

Check whether the heater water tank is blocked.

The warm air tank is in the cab. Because the owner used inferior antifreeze or failed to replace it in time for many years, the warm air tank was blocked, and there was no hot water flowing in the warm air tank, so there was no warm air blowing out. In this case, you can clean the heating box first, and if the problem cannot be solved, you can only replace it with a new one.

Check whether the water pump is good or bad.

The water pump is the main part of the circulation system. If the impeller of the water pump is badly worn, the heat of the engine cannot be taken away and flows, which will also lead to no warm air. You can take the pump apart for inspection.
