Hello friends,

Today I was driving to my house and I turn A/C on, it is working fine but when I hit in low start to do a noise like this:


Any of you guys have and idea what could it be, and how to solve it?
I can say that the AC accomplish his function but the issue is that noise like a stuck fan

Kind regards,

 

Sounds like a broken actuator jumping teeth. Does this only happen when you change temperature or vent settings? And does it vary with fan speed?
