I was motivated by the -5 deg F temperatures and snow today to finally test the rear compartment heating (cabin heat, not seat heaters). In the front, with the temperature set to 65 deg, after a minute I'm getting toasty hot air from the vents. But in the rear, with the temperature set to 79 degrees and fan on 7 or 8, after 5 minutes I'm getting cool to mildly warm air through the 2nd and 3rd row air vents. So before I schedule a service appointment, I thought I'd ask if others are seeing the same heater performance and is this normal for the MX? Thanks.
