As suggested I replaced my cabin air filter to rid my annoying whistle from under the glove box earlier this am...Although I am super happy I changed the filter, as it had more leaves in it than my front yard, it didn't fix the whistle/whining noise...Anyone have any other ideas?

It's not the fan making a whistling noise is it?
You may need to be a bit more specific than "My car has a whistle coming from the passenger side".
Change passengers, maybe you'd prefer a humming noise!!!

 

No it's not the fan. Nor the motor. Or anything associated with the two. I've pretty much isolated it to the assembly leading to the hoses. Appears that one of the hoses has a leak. I am tearing it all out this weekend and will post what the issue is. But thanks for your response.
