HOW DO I FIX A RATTLING SOUND COMING FROM MY DASH WHEN THE AC IS ON?

2009 Ford Fusion • 39,000 miles

When I turn the AC on in my 2009 Ford Fusion SEL V6, a rattle starts in the dashboard. If I increase the fan speed to maximum, the rattle will all ways go away, but it sometimes comes back. It is a soft rattle, but it gets kind of annoying. It is there about 90% of the time. It sounds like a ventilation fan on a personal computer that is out of balance or is hitting a small piece of plastic.

What could this be, and how can I fix it?

The only thing you can do is check for something that is loose. If it only happens with the fan, check to make sure it is tight.
