Super weird noise from the AC !!!

Leon007 · 09-26-2018, 09:11 PM

Hi my 2017 M6 Gran Coupe has only 7000 miles. When the AC is on, I can hear some buzz and plastic rattling noise coming from the AC vent. But when AC is off, that noise goes away. That noise has been existing since day 1.....

Any solutions ??? Thanks a lot !!!

Why not bring it to the dealer and complain?

What if you just use the vent (air blower) without the A/C. Any noise is not normal.

Just using the vent (air blower) is ok, but when turning on AC, that noise comes back...

Maybe some debris in/at the A/C compressor belt in the engine compartment. Or the compressor it self. The way to the dealer is indispensable.

I'd have them take the filter out and inspect it at the very least. Probably a leaf or some junk stuck in there.
