My car's been doing this climate control after-shut-off venting since I bought the car in December. It sounds like the electrical AC fan too. Not worried about it.
A funny thing though, while were on this subject. Has anyone noticed their AC/climate control "surge" in speed/intensity while the AC/climate control is on? I have noticed this sometimes. The fan seems to burst or surge to higher revs for fractions of a second at a time and then slow back down again.
This is not always, just sometimes. Any ideas? No big deal, but I was just curious. Kind of sounds like the AC is having an epileptic seizure.
