Noise before the engine start ?
I don't know if this is normal: When I turn the key to ON position in the morning, without starting the engine, a noise would comes on in a few seconds. Sounds like a electric motor. (it is not the A/C fan as I turned the air off). After I start the engine, I can still barely hear the noise. I don't know if the noise keep going or turned off as I'm driving. Does anyone knows what noise is that? Thanks.
