All,

I have an 04' coupe that I recently purchased. I have had this strange high pitch whistle noise from right under the passenger side glove box. This only occurs when I turn on the AC and immediately after I turn it off. Does anyone know what assembly is under the glove box? Or what might be causing this? It appears there might be a filter of sorts that is not sealed that might be causing the high pitch sound.

Please help.
