Various Noises From Vents

Post by jagstyles » Wed Oct 17, 2018 1:56 pm

I have noticed two very distinct types of noises that seem to come from the front vents of the vehicle.

The first one is a knocking noise which typically happens within the first few minutes of starting the vehicle. It'll knock knock knock and then eventually goes away within a few minutes.

The second is more subtle but even more annoying once you notice it. It's a that resembles the sounds crickets make but it's constant and only happens when you press the acceleration pedal. Even the slightest press of the pedal will initiate the noise and I typically hear it fro the driver side vent closest to the window. If I raise the volume of the radio, it typically tunes it out but it's the kind of noise/sound that once you hear it, you cannot unhear it and you'll always notice it. I just find it strange that you only hear it when you are using the acceleration pedal.

Anyone else notice these sounds or have any solution?
