Motor sound when engine is off

[viper8548]

I've been noticing this for a while now. My car emits a motor noise about every 5 minutes, I don't know exactly where its coming from but it sounds like the front right side of the car.

The sound sounds like the motor sound when you are closing the sunroof, power windows etc.

Anyone know what that is? sounds like a massive battery drainer

could be the a/c compressor?

i know on 2 of my mazdas, it used to make a funny noise once and a while after it was off.

I was washing the car and it was making that noise for 4hrs constantly, doesn't seem like a temporary thing.
