Quick question: every morning i hear this 'faint' buzzing sound for a sec when i start up my car, is this normal?

 

i get it as well, i think it is normal.

 

What kind of buzzing sound? Where is it coming from? I don't think I've ever heard it.

 

Fuel pump?

 

ABS self-test?

 

At -28 C this morning my car made a really bad buzzing sound which came from the heater fan. Actually it made all types of noises. My power seat didn't work, my door latch froze so I couldn't keep my door closed and it took about 20 minutes to warm up. I'll never leave my car outside on a night like that again.

 

^ 20 minutes to warm up? You didn't let it idle that long before driving it did you?

 

No, just a few minutes then took about 20 minutes of driving for decent heat to actually come out.

 

I would get the buzzing noise checked out at the dealership. Does it only do it under cold start?

 

I get it as well, usually 10 seconds after driving and then it goes away in a second.

 

the buzzing sound only happens in the morning. It feels like some kind of sensor(s).

 

a fly or bee?

 

i was thinking about humming bird.. but who knows..

 

AN electrical type of buzzing sound? Or is it a mechanical type?

Where does it come from? Interior? Engine bay? Under the car?
