Rattling sound on Yaris when A/C is off - Toyota Yaris Forums

Yaris044 · 08-27-2020, 03:00 AM

I own a toyota yaris 1.3 automatic. I have a weird rattle sound when idle and very noticeable when starting acceleration but only when the A/C is OFF. As soon as I turn A/C on, the rattling sound disappear.
Maybe something with the A/C?

Most likely the a/c compressor clutch.

Konstantin88, please check out my Red Yaris restoration thread. I discovered how you can access the large inner cavity that is prone to rust.

Just sharing my experience with rattling sounds with AC engaged and idling.... It was the exhaust heat shield that rusted off and with specific engine revs (hot engine, AC on, idling) it got rhytm and started shaking like mad. I took it away completely and driving a few years since then.
I know that this is not the case for your OP but someone may find this thread later when searching for answers.
