The car heater water tank is blocked.

You can blow it with compressed air to see if it can be unblocked. It is necessary to remove two pipes from the heating water pipe and blow through the heating water tank. This method is simple, but it can only be used when the inside of the water tank is blocked by softened sludge. It is inevitable that cars will produce exhaust gas after running for a long time, so riders should pay attention to car maintenance at ordinary times to avoid the water tank and other parts being blocked by waste. In addition, a simple way to solve the blockage of the warm air tank is to find a washing station, and then let the repairman remove the inlet and outlet pipes of the warm air tank, and then wash them back and forth with the water gun of the car wash until the washed water becomes clear.
