Took my 750iL out for the first time this year yesterday. The windshield got hit and cracked by a flying object, a rock, I guess. Safelight's quote was $986, but I don't think that's an OEM windshield. Any thoughts? Also, with the hvac system on auto, exterior temp 50 degrees F, interior temp set to 72 degrees F, there's hot air blowing out the defrost vents. Is this normal operation? Anything I can do to make it not do that while on auto? (I know I can set the air control to come out the dash vents and that shuts off the defrost and footwell vents.) Is there any way to get cold air to come out the footwell vents and defrost vents? Just wondering if there's something wrong with my car. It sure seems like it.
