Whirring sound after starting up.
Texas is having a god awful heat wave. The last couple of times I've started the engine after it's sat in 100+ heat, there's a sound like a fan that lasts about 15 seconds. Doesn't seem to be the ac, and it doesn't sound rough or scraping-just sounds like a blower motor. I've had the car for a year, and this noise is new. Any thoughts?
