First, before you ask, the temps are set in SYNC to "HI" for both driver and front passenger. Ok, that out of the way: the right heating vents up front put out cold air much longer before they eventually warm up. This is a relatively new phenom. Often by the time the right side gets warm, I've arrived at my destination so it's moot. When it's 19F outside, and the car's cold, it obviously takes a while for the heater to start putting out warm air, but when the driver's side dash vents are finally putting out warm air, it's still like frigid air coming out of the front passenger's dash vents... and it stays that way for a good while. Anyone had this problem before? Is there more than one heater for the car? Like, L and R? Trying to figure out why I'd be having this problem.
