It sounds like you have a vacuum leak in the line. I would suggest taking out the heater controls and following the lines until you get a the main junctions which might just be behind the glove box. most likely one of the lines came off and all you have to do is replace the hose line.
hope this helps you and let me if you need anything else

thanks tom

What part controls switching air/heat from defrost to bi-level to floor & where is it located?

In the attached drawing, Part 32 moves Part 26 to direct the air flow to the desired locations. It uses vacuum to operate. The actuator may be bad or the vacuum hose my have come loose when the heater core was changed. With the car running but the blower off stick your head up under the dash on the passenger side and see if you hear a hissing sound. If so it's probably just a vacuum hose come off.

1996 Montero Heater Blower not working

I assume your heater setting is electric control, if so either your defrost and floor heat switch failed or wire problem. For the air not hot, check the heat control valve on the top of the hose it should be in front of the firewall. I don't know your car is using mechanic valve or electric control valve. Anyway check there first. Good luck.

Could be the control switch itself. Or possibly the actuator that moves the door from defrost to heater. With the heater on, try switching from defrost to heat and try to hear if you can hear anything in the dash operating.

My Buick does not throw any heat from the defrost or floor. The heater hoses are hot goinginto the dash

Either the heater control valve or the vacuum switch.
If you look down under your dash towards the glove box you will see the heater core cover. On top you will see a lever, conected to a rod.
If you pull that as you have your blower fan on you should be able to manually adjust that lever until heat is flowing.
Please let me know.

What is a blender/ it is suposed to a part of the heater area

The "blender" would refer to the blend actuators that change the flow of air from floor to vent to defrost or combinations. Properly working blend doors will allow you to direct air to the dash vents, the floor, the defroster, the floor and defroster or the floor and dash vents. If it is not working the heater will still work but you will hae no control oer where the air flows.

Heat not coming out of vents,but heat will come out of the defroster. 95 cadillac

Good news is there is no problem with the heater. Bad news is the Flap didn't open to direct the air flow through the vent so all the flow going to the defroster. Part is not expensive, but labor is a concern since the work is at the dash vent. Cheers

No dashboard heat output

The climate control was poorly designed on these cars.

There is only heat on the floor and defrost settings, due to the layout of the ductwork.
