This blows... vent trouble

2000 TJ Sahara

The air flow in my JEEP is stuck on defrost instead of front vents. No front vent flow, zero.

After searching the forum I found a vacuum diagram and found no (visible) leaks in the system from end to end, with the only unchecked part being the line going into the firewall since I have no idea where that goes in order to check it?

In addition, I have already replaced my relay control switch, vacuum switch, blower motor resistor, and even blower.

Anyone? Thanks
