There is a mix damper inside your duct that controls the heat over heater core and ac evaporator that to your floor and one to your defrost. it is probable an electric actuator, that is not functioning properly. If yu can locate it and manually move it, you might have to remove the actuator motor first, you should be able to figure out your problem, I hope this helps! merry Christmas!

CHECK THE HIGHT OF THE HEATER MATRIX IN THE CAB , IF ITS HIGHER THAN THE FILLER/EXPANSION TANK. THEN ITS AN AIR LOCK, LOOK FOR THE HIGHEST PIPE AND SEE IF THERE IS A BLEED VALVE, IF NOT TAKE BOTH PIPES OFF THE MATRIX FEEDS AND FLUSH OUT TO SEE IF IT IS BLOCKED, AND RECONNECT LOWEST PIPE FIRST AND FILL SYSTYM TILL WATER APPEAR FROM TOP AND RECONNECT RUN MOTOR, AND KEEP TOPIN UP

THE 97-04 MONTANA HAS THE 3.4 ENGINE WHICH HAS AN ISSUE WITH FAULTY INTAKE MANIFOLD & HEAD GASKETS WHICH FAIL TO SUSTAIN CIRCULATION IN THE COOLING SYSTEM AND CAUSE AN INAEQUATE HEATING SITUATION. REPLACE WITH FELPRO GASKETS AND YOUR PROBLEMS ARE OVER, PROVIDING ENGINE IS NOT DAMAGED!

Are you sure it has a block heater on it? The plug is usually around the front grill but unless someone added it as an aftermarket option, it probably doesn't have one.
