Air conditioner ball

Hello friends, there is a sound from the front, when the engine is running, but when the air conditioner is switched on, is there any reason to know?

The tensioner bearing that comes from the v-belt might be defective, as I guess, the free sound. I would recommend that you have a look at the air that may cut the sound when operating the air conditioner. you can control it yourself.

Do you think it would cost a lot?

Not from the air conditioning ball, right?

only the tensioner bearing and the belt will change if the belt is 30-40 TL in the bearing and 50-odd something is wrong.

How can I control it myself?

open the hood of the teacher, where the sound from idle can come from the air conditioner compressor. it might even be more enlightening if you shoot a video.
