21 F-Sport, in the peak of winter I am noticing a high pitched whine coming from the fans when heat is on. I don't think I heard it during hotter days earlier. It's most audible when the temps are cold - 28F or thereabouts. Makes me think it only happens when fans are spinning at high speeds. Google says many Camry and Corolla users have complained about similar issues but without resolution.

Has anyone else has experienced similar whine and if so was there a resolution? Between the known unresolved Camry/Corolla issues, parts and labor availability and the nature of the problem (the dealer could just say I don't hear it lol) I am not sure if I should pursue a fix or just accept that it's going to bother me in winter.

 

I took my car in for the 12-month service and a few days later started hearing a similar sound! I'm thinking it might be a cabin air filter issue, but haven't done any research yet. I'll post a response with the answer if I find it!

 

post a video... no way of making any kind of call based on "i hear a sound"
