No Heat!

[ChiefRider]

So today, October 10 is "Moment of Frustration Day". I think that is more accurately EVERY day as the owner of an E53. So on to the problem du jour.

The AC works fine in my car- No problems there (as far as I can tell). But this morning was the first time I really needed to use the heat. After driving a full 10 miles in 50f ambient temperatures, the air blowing from the vents was at least not cold anymore! IDK, maybe I was just numb by that time. I turned it off.

60 miles later, I thought I would just check to see what was coming out of the vents- Ambient temp air, that's it. Now that winter is approaching I can't ignore this issue. Where should I start with this one?

Thanks
