Radio hums when car is turned off...

ErinFaulk · 10-19-2009, 11:54 AM

Hey guys-

Took my car in to the dealer for a few things, but one of the reasons was due to my radio constantly humming after I turn it off. It sounds like it is coming from the radio, they stated that it might have been the battery, so they replaced it. Yet it still continues to buzz/hum after I turn off the car, or even when the car is on but the sound system is off.

Anyone have this problem, any idea what it could be?

Mine will buzz if the ipod cord for the headphones is not plugged it to the ipod.

but thats all i can offer you

This is old, if you are talking from the car or inside from the dash, its the cars computer and or the dvd/cd disc making sounds while thinking.

But if you are referring to the radio with sounds coming from the speakers itself. then i dont know.

Fiddle with the headlight selector switch. That did it for me.

feel your driver side quarter panel and see if its vibrating. if it is, open the trunk and open the plastic panel on the same side. you'll see the logic7 amp and the cooling fan will be humming loudly. the cooling fan for the amp stays on a few minutes after the car goes off. freaked me out the first time i heard it. hopes this is what u were talking about
