Sound coming from air on?
Hello, it's me again.
I had this sound awhile ago but it hasn't happened since then. I'm pretty sure it only happens when it gets cold, It starts up when I wait about 2 minutes for my car to warm up then it starts doing this then goes away after about 5-10 minutes of driving it.
I don't have the air on full blast, only on the lowest setting. No defrost on, Just the heat a 75 with the air low.
It sounds like it's coming from the heater core, Not really sure.
Anyone have any other ideas?

Sounds like the AC fan bearings are going, here's how to test-
Put the temp control on hot but the fan off. If you still have the noise you likely have air in the heater core. If not, turn on the fan at the same speed as before and see if noise begins. You should have your answer.

Would it be necessary to change the bearings ASAP? Or may I wait awhile?
Thanks for the response.

If it is the fan you can run the heat till the fan seizes. The noise usually gets louder until the blower dies, then you change the fan/motor as 1 piece. IF that’s the problem there's no harm in running it till it dies, and it won't cause other problems. Gl!
