I have a 2005 X3 with automatic climate control. I can't seem to get the
heat to work correctly. The A/C works fine but now that it's getting cold, I
need heat. (I bought it used and this is the first winter I've had it.)

If I leave the auto control on, and turn off the a/c button, all I get is
cold air coming out of the center section. I try raising the auto temp but
it does no good. If I switch to manual air flow, I can get warm air to come
out of the floor section and window section, but the center console still
blows cold air. I close the air recirculation so only the cabin air is being
heated. The A/C button is off.

Is there anything I'm doing wrong or any suggestions on how to get it to
work correctly. And, if in the manual mode I switch on the front window
defroster, it shuts off all other air flow.

TIA

It should give the cabin temperature that is set regardless of AC on or
off. Sounds like the unit is faulty. Does the outside air temperature
indicator read correctly? This has an effect on the interior heater.

This is correct operation - the entire heater output on max is directed to
the screen to defrost it as quickly as possible.

I don't know if the X3 is the same, but on my 5 there's a thumbwheel
in between the two center vents that controls the air temperature from
those vents separately from the rest of the car. If that thumbwheel
was set all the way down to its coldest setting, I'd have exactly the
conditions you are describing.

That's what I thought too. It should be obvious, but blue is cold, red is
hot.
