Heater stooped working

[jclass]

I have a 2003 Y34. Last night, and in the middle of the recent blizzard that hit NE US, my heater stopped working (Go figure!!). I went to check fuse box under hte hood and everything is fine. I went to check the "other" fuse box in the passenger compartment, BUT I CAN'T FIND THE @&%$ THING". Can anyone help? I will like to know where it is and if anyone has had this problem and a have an "easy not so much costing" solution, it will be great. I have found in the past that this site is very useful.

Thanks for your info!

When you say it stopped working, does that mean the fan stopped? The air was cold but air was blowing or the vents changed to blow somewhere else?

Different things are suspect for each description.

If the fan's still working you might just have some air in the coolant system -- it's about $65-$95 to flush the coolant line.
