On your Navigator the most likely failure that will cause a lean condition on both banks is the PCV tubing. Start at the PCV valve in the passenger side valve cover and follow it to its connection to the intake manifold, and closely inspect the rubber elbows in the tubing for vacuum leaks.

P1450 = Inability of Evaporative Emission Control System to Bleed Fuel Tank.
This means you have either blockage or a leak in that system. Or possibly your charcoal canister is bad. Do you regularly top off your gas tank? This is usually what makes a charcoal canister fail.

Since your blower is working and it is a heat issue,thats where we'll
start,First thing is have you checked the coolant level in the radiator when
engine is cold,make sure it is filled to top,next verify you have coolant in
reserve ,Start your van and get it up to normal operation temperature,If your
heat gauge on the dash works correctly it should be 190 degrees,Now lift the
hood and locate the two heater hoses going into the heater assembly at the fire
wall,Both hoses should be hot to hold on to,if both are hot and no heat inside
your problem will be the blend air door in heater assembly.
if neither hose is that hot you need to replace the thermostat in the engine to get it up to 195 degrees.
if one hose is hot and one is luke warm then the heater core is blocked and to blame. hope this helps you.
