Heating Issues

ok i have a 96 850 na with 199k

PROBLEM

my problem is that i was getting poor heat from my heating system. so i did the basic steps... search on vs for hours apon end to find the answers. well i replaced the thermostat and the ect and flushed the coolant. my next step was my heater core . i just order one tonight. but when i went to the store to by some tools i found that my heat was working great. when i first had the problem it was around 18f and today its roughly 30f. i checked the recirc door arm and that is broken. will replace tomorrow. but i'm wondering if i was just sucking in freezing cold air and thats why my heat wasn't pumping out hot. i can move the fresh air dial and that seems to open fine . and i checked the heater core and its not leaking. if you guys could chime in tonight that would be great so i can cancel the heater core tomorrow if i have to.

QUESTIONS:

1 could i be sucking in cold air . and that is making my heating system not work properly.

2 how can i check to see if i am sucking in air.

3 should i just deal with it

4 or is the heater core shot and i need to get a new one

thanks Mike

You should still get plenty of heat even without recirc activated. I think my core is going (I can smell it when I first start the heater) and I still get plenty of heat.

When it gets cold out I always turn the fresh air dial (not recirc) off so I get warm air out of the center vents.
