Update.
I ended up buying a new blower and now the high pitch noise is gone. Very quiet now.
It very easy to replace it yourself.
1. Remove cabin air filter in the back of the glove box. Remove any debris and replace filter if needed.
2. Underneath the glove box pull off bottom cover. Very easy.
3. Unplug power cord. The release button is a bit stiff and you mag need a flat head screwdriver to push it in while you pull.
4. Unscrew the 3 screws. You can use a ratchet with a 8mm Socket or a T-25 torque screw head. The back screw is a little difficult to reach. You will either need a very short screwdriver or a small ratchet to get it out.
It took me about 20 min.
