Hum buzz noise coming from radio area.

Any help? 2002 s60. A sensor or a fan? Just annoying when listening parked.

I'd listen for the sound and push against the dash on top near the sounds.
Is it all of the time or just AM radio.

All the time. Dies off about 60 secs after key pulled.

does turning off/on the climate control change anything? Does manually changing the blower speed do anything? does it happen only when the engine is running or can you hear it with the key on position II? It could either be a trim piece resonating with engine vibrations, or the climate control blower or one of the blend door motors.

Funny. I noticed the same on my car. I am also hearing a similar buzzing sound near the ECU TCM box in the front. By removing the relay FMA2 the sound near the TCM goes away. I will check the radio area and see if this is also related.

I am having intermittent electrical problems. Sometimes throws Throttle sensor codes and other problems. Maybe not related.
