Hi,
I have a 2011 Mazda 3 GX. There is a squeak when I have the A/C on or the defroster vent is selected. It is a single squeak that happens every 20-30 seconds. It happens only on certain vent settings, the windshield/defroster...or any vent setting with the A/C on. I'm wondering what this can be and how to fix it. Any help is appreciated.
