Sagitar warm air is not hot.

The reason why the vehicle warm air is not hot is very simple compared with last year. Generally, there are two major factors: first, hot water can't reach the warm water tank, and the warm water pipe is blocked. First, some old cars have too much foreign matter deposition in the cooling cycle, or use antifreeze with poor cleaning effect, which affects the blockage of water pipes. Such a problem is enough to clean the engine cooling system. The second is the failure of warm water valve and regulating valve. In order to ensure that the antifreeze heats up quickly after the engine is cold started, most warm water valves will cut off the interconnection between the warm water tank in the car and the engine. If the valve of the warm water tank is stuck or there is an electrical control failure, it will affect the entry of high-temperature antifreeze into the warm water tank. Only by touching the two warm water pipes in front of the engine compartment warm water valve can this fault be solved. If one is hot and the other is cold, then there is something wrong with the warm water valve or warm water piping system. Second, the hot air is not sent out of the air outlet. There are three specific situations: 1. The air conditioning filter element is blocked. 2. The air conditioner heater door is stuck, the adjusting cable falls off or the motor fails. 3. The air supply of the blower is too small. For such problems, check whether the air conditioning filter element is dirty and blocked, and whether the air supply volume of the blower is insufficient. If these problems are eliminated and the failure problem depends on the maintenance of the network, then it is necessary to consider that there is something wrong with the damper adjustment of the air conditioning duct.
