2001 Chevrolet S-10

Heater problem
2001 Chevy S-10 6 cyl Two Wheel Drive Automatic 156000 miles

I have a 2001 Chevy S10 Extreme Blazer. I am in the middle of changing the heater core. I have the entire dash removed from the vehicle. The only thing keeping me from removing the heater core, is the blower vent assembly in front of it. I have removed every visible screw, bolt and clip from both sides of the fire wall. And it still will not budge! I can see the top of the heater core, but still can't get it out! What do I have to do to remove the blower vent housing, or to get to the heater core
