请教懂车大神 - 车打着火后，手套箱位置发出格拉格拉的声音，持续几秒钟

[翻墙五毛]

像是电机带动皮带走到某个位置。关发动机之后，又是差不多同样的声音，似乎是皮带归位。这是啥玩意的声音

是空调启动的声音吗？

[catoh]

我猜是空调控制冷热风混合的blender door电位器磨损，或者齿轮崩齿，总是走不到位来回动。

试试看开到最热或最凉，声音应该有变化。

如果确认是这个毛病可以把电位器打开清洁一下，掰一下弹簧片之类，零成本，很容易修好，或者整个换actuator，也很便宜。Google一下你的车型号就好

100% broken actuator

Find a good actuator because many cheap ones don't have enough torque to last.

Depending on car, changing actuator can range from 20 minutes to 4 hours.

Since yours is below the glove box, it seems like a 20 minute job.

汽车执行器多了，你说的应该是空调的吧

是的

Blend door actuator or air distribution actuator
But they all the same one. Just different locations.
If you have dual AC zones, then you have 2 blend door actuators.
