Radio Reception after Car Detailing

[gee69off]

This is my first post but this exact thing happened to me. My radio is fuzzy as hell and when I turn the defroster off its crystal clear. I'm a dumbshit when it comes to cars, so please excuse me, hopefully ill be learning more soon. Where and what exactly is the C-pillar? Lol and being every part in a car illiterate, how am I going to locate this noise filter? Help the yaris handicapped...

On another note, CTScott, its members like you that made me join this site. There are so many cool projects with great instructions from members like you, and you're incredible knowledge and your willingness to share that knowledge make this such an incredibly awesome tool to me learning about my car! Keep it up and thank you!
