Weird sound when I turn on car AC


Senior Villager
Wadau, there's a weird sound when I turn on the car AC. It's just a one off sound coming from the engine bay right after I press the AC on button. After that the AC continues to function as normal. Diagnosis and solutions please?
Service your AC by buying a new filter, checking the fan or replacing the fan pulley.For some models of vehicles , they have fan belts for the AC, tighten the belt or replace
