Cruze has no heating. What happened?

There are several possible reasons why there is no warm air: the air conditioner blower is damaged, the hot water valve or the vacuum driver of the hot water valve fails, the engine thermostat fails, the heater water pipe is blocked or the heater core is blocked by dirt, and the air distribution pipe of the temperature-controlled air conditioner is broken. According to the above reasons, we can test whether the two hot water pipes are hot or not: 1. If it is hot, it means that the water temperature is still fine. Continue to check the hot and cold adjustment of the air conditioning panel.

If there is no problem with the water temperature, we should first adjust this adjustment to the hottest side. If it is adjusted to the hottest or not warm, there is something wrong with the door for adjusting the hot and cold, that is, the damper does not open or is half open. If it is motor adjustment, it may be that the motor is broken.

2. If you feel that the hot water pipe is not hot, it may be a problem with the thermostat. Maybe it was opened too early, and the water dissipated before it completely rose, so there was no hot air or the hot air was not good, and a new thermostat was needed.

Finally, we can also clean the warm water tank to see if it is too dirty and hinders the circulation. This can be achieved by removing two water pipes and flushing them with a high-pressure water gun.
