When I turn on my rear window demister, I get constant cracking through the FM stereo. Not so bad when I stop at the lights. When I turn off the demister, it goes away the radio is clear. All FM bands it seems. But AM radio is fine. 
Anyone else get this?

Heater element & antenna are built into the rear glass. Check all connections especially the sticky pad at top centre of the screen. Give it a shove.
