Grinding noise when AC on - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

Hello,

When and only when the AC is on. I hear I grinding noise when I am driving and then shift to neutral. As I am braking the noise will come

There is no specific RPM range where the noise come, but it comes infrequently. Maybe it comes while I am driving. I don't hear it though, full exhaust changed.

The power steering is electric, there is no fluid. Have you changed wheel/tire/alignment recently? Is your Power Steering Warning light on?

You need to take a video of the sound so we can get a better idea of what it is. Right now, it's difficult to tell what it may be.

Yep, either a video and/or a more complete description of what you are feeling/hearing.

And also, I presume you used power steering fluid when you changed the fluid. If so, you need to figure out what fluid you did change (probably clutch or brake) and flush the affected system. Or things may break.

Let's hope it didn't go into the engine oil fill...

what could he have poured the PS fluid into? the engine oil cap says oil on it I believe and the brake MC is pretty obvious. maybe clutch? or maybe just the coolant overflow lol. hopefully he didn't pour it into the brake reservoir otherwise that is bad news if he drives the car and its sucked into the lines
