Scratching Sound Coming from Passenger Side AC Vent
Hi everyone,
Long time lurker for my mother's MB's... but only 2nd post here. Thank you for this amazing community.
I am a proud new owner of a 2015 C300 4Matic. I just purchased it CPO from Silver Spring, MD just a couple of weeks ago.
A few days after I started driving the car, I started hearing the noise coming from the Passenger Side AC vent, almost inside of it. At first it sounded a bit like static, but upon further listening, it sounds more like a scratching/whirring/mechanical/static like sound that comes and goes.
I of course did a large search for others with similar problems and I think some come close, but I can't be sure because they don't have soundbites for me to listen and compare.
I went to the service guys at MB and they opened up the hood, popped the air filter area out and said it could be dried up leaves and debris that is making the noise. Funny thing is it seemed to work for a couple hours, no noise. The next day it's back.
It seems to happen more often while driving, at low RPMs... but I'm hesitant to say it has anything to do with the engine, the sound is coming from right behind the passenger vent.
.
You can clearly hear it here. Any help would be great because I just bought this car!
Much Love,
Butter
