My wife's 328xi doesn't seem to want to blow hot air in the cabin. Someone suggested to check all the temp settings in iDrive, but there's no iDrive on this car.

After a "spirited" drive of 30 or so miles last night, it still didn't want to blow hot air. That's with both temp knobs turned up to 84 degrees and the dial on the dash turned to red.

I don't think the thermostat is stuck... we've not had any issues with overheating.

I get a bit of warm air out of the passenger side vents both top and in the footwell, but only cool air out of the driver's side. I'm guessing a blend door is stuck or maybe a stepper motor is shot?

Anyone have any ideas before I take a 120mi drive back to the dealer?
