08 Accord Warm Air Problem?

08 Accord, the warm air is not hot, the right side is a little hot, and the left side is cold. 08 Accord (check the transaction price | model details), the warm air is not hot, the right side is a little hot, and the left side is cold. First, the heating system is not hot. It can be divided into two reasons, one is caused by the engine cooling system, and the other is caused by the poor operation of the control mechanism of the warm air. In maintenance, we must first determine which cause it is, and then carry out corresponding maintenance. The method of discrimination is simple. Look at the temperature of the two inlet pipes of the warm air small water tank. If both pipes are hot enough, there is something wrong with the air flow control mechanism. On the contrary, if both pipes are cold, or one is hot and the other is cold, it is a problem with the cooling system. Second, the possible problems of the cooling system: 1, the thermostat is always on or the thermostat is turned on too early, which makes the cooling system carry out a large cycle too early, and the outside temperature is very low, especially when the car is driving, the cold air quickly cools the antifreeze, the engine water temperature does not come up, and the warm air does not heat up. 2. The water pump impeller is damaged or lost, so that the flow through the warm air small water tank is not enough, and the heat can't come up. 3. There is air resistance in the engine cooling system, which leads to poor circulation of the cooling system, resulting in high water temperature and lukewarm air. If there is gas in the cooling system all the time, it is likely that the cylinder pad is damaged and the gas leaks into the cooling system; If the inlet pipe of the small heating tank is very hot and the outlet pipe is very cold, this situation should be that the small heating tank is blocked and should be replaced. Third, the air volume control mechanism problem: 1, the car's warm air blower blows the heat of the warm air small water tank into the cab. If the air volume is insufficient or the distribution of cold and hot air is not good, the heat of the small water tank of the warm air cannot be dissipated, which will also cause the temperature of the warm air not to rise. At this point, first check whether the filter element is dirty or blocked, clean it, and replace it in time if necessary. 2. Check the operation of each gear of the blower to ensure that each gear has sufficient speed. If the knob is set to the warm air position, the air volume is large enough and the wind direction is normal, and the cold air is blown out, check whether the cable of the hot and cold air control flap in the warm air box falls off, whether the warm air impeller is damaged, whether the flap falls off, etc. After troubleshooting, the warm air will get hot. Fourth, to sum up, it is about the introduction of troubleshooting methods for the reasons why the car warm air is not hot. I hope it will help you. @20 19
