I have a 2014 Silverado 1500 with about 26,000 miles on it. Just last week after I took it in for the cabin air filter to be changed (which is probably unrelated), my a/c and heat both make a noise somewhat like a prop airplane after i turn it past half. It's intolerable. I can't talk on bluetooth, can't listen to music at a comfortable level, and is just very frustrating.


This video shows my exact problem, except it's not cold where I'm at. I took it in to the dealership and they said other vehicles that are the same model and year make the same noise... Mine didn't make this noise until last week.


Is there anything I can take them to get them to look at the blower motor? It's driving me insane as it's still pretty hot where I'm at and I have a pretty long commute during the day...
