Default Heater doesn't push warm air...

Hey guys. When I have my heater on, I can not feel any warm air (let alone any air at all) come out of any of the vents.
When I have my defroster on, I can feel just a slight amount of heat billowing out the top vents. Now, when I turn my A/C on, I can feel medium-strong gusts of wind coming out of even the upper center vents.
Last year, my heater fan groaned a lot and sounded like it very much wished it were dead in the morning. I have a few questions-
A) Are the heater fan and A/C fan the same fan? (The one on the passenger side, between firewall and coolant recovery tank).
B) Is there any chance this is just a burnt out heater control or burnt heater control part?
C) ...is there any chance this is the heater core?...
Thanks in advance. I go to school at 8 in the morning and it's in the mid-thirties. Plus, I like to drive with the windows down, so... I could REALLY use a heater.
-Steve

a. Yes.
Sounds like you need a new blower & make sure temp. lever is working. Possible vac. leak to or at A/C/vent/heat switch. Heat comes out near floor in front of console. Vent ducts may need sealing.

Post more info.

Cool. I'll replace the fan this weekend and see where that gets me. You guys know any tricks to pulling that sucker out? Do I have to yank the coolant recovery tank? It seems like it's at a rather weird angle.

You should be able to hear the fan motor running, check there first then start looking for a vacuum hose leak under the dash. Happy hunt'n
