Put your hand on the heater hoses as close to the fire wall as possible find out if both hoses are hot.Do this when the vehicle is cold allow car to heat up with heater open and running.If both equaly hot then heater core at fault.If different check water supply to cold hose.

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.

It is possible you have air bubbles in the cooling system. Loosen radiator cap or resivor cap and let idle for about 15 minutes. Tighten cap and drive and see if that helps. REMEMBER TO START THIS PROCEDURE WITH A COOL MOTOR AS THINGS WILL BE QUITE DANGEROUS DUE TO COOLING SYSTEM PRESSURE WHEN HOT.
Testimonial: "Hi;Your information confirmed what I thought and bought a new radiator cap and checked over flow hose and tank it is hot again seems fine.Thanks Randy"

Stick your head under the driver side dash and look on the side of the blower motor check to see if the wire to the damper is moving through the small plastic conduit. over time the wires lose their rigidity and instead of moving the damper it will bend. Let me know if these look normal
