My First Issue Looking Fir Guidance

Hi

I have just experienced the first issue with my 2007 Mazda CX-8.

I just noticed that while the radio works fine when I put on the rear defroster it switches to almost 100% static.

Ive played around with the rear defrost button and anytime I pressed it the radio immediately becomes staticy.

Is this a known issue?

Not sure if this is also a problem but anytime I turn the car off the interior fans go on for about 30 seconds.

Appreciate any suggestions.

I believe the radio antenna on the 2007 CX9 is embedded into the rear windows and is part of the rear defroster wires.. There may be a break in the antenna So when you turn on the defroster. It's causing the static.
See link.... Seems like a common issue
