Hello,

This sounds like a blend door actuator is out causing the noise which is common. Here is a guide to help you see what you are in for when doing the job:

Here is the location for your car. The best thing to do is put your hand on each and feel which one is giving you the trouble.

Check out the diagrams (below).

Let us know what happens and please upload pictures or videos of the problem.

Cheers, Ken
