When I am listening to the fm tuner and switch on my rear defogger, static obscures the radio signal. Isn't that thing just a nichrome type heating element? What would cause the radio to gain noise like this?

A bad ground that is common to both circuits, that's what.

 

Sometimes I'm a little slow.

I have only had trouble with this when my alternator was going south; bad diode...........now my FM tuner sounds clean......it's the AM tuner that is hard to clean up.............Medium Frequencies are tough when it comes to ambient noise; especially overhead power lines................I digress.............Next time I jump in the car, I will see if my rear window heater has the same effect........very interesting.
