The seats are hot, but the heat that comes out of the vents are cool, and temp is on 80 degrees.

Chances are you need to go into the iDrive settings for the "vent settings". from there you can change the general thermostat (heater) setting. I would start there first.
This is a correct answer. There is a bar graph that switches it from cold to hot or vice versa. It is in the I Drive system and I learned the hard way one winter, but the dealership showed me how to adjust. Very Simple!
I have tried this a number of times and still cold air coming out of all vents. Is there anything else I could check before I take in to delaership?
