    the one that i can see is just above the passengers left foot up against the hump. i can see the end of the shaft, it did not respond to any change of temp or direction. judging by your response i start with this one. how many of these motors are there?

    Thanks for your help, I appreciate it and the wife evenmore if the heat hits the floor.

    OK. turns out this model has both electric and vacume actuators. the vacume actuator high on drivers side had 3 of the 4 hoses disconnected with the one for the windshield being the only one attached. it appears someone had been in the dash before but did not hook these up. everything works good now. thanks for your help.

You will have to locate the actuator motor,that is defective,by process of elimination,finding it,and adjust the selector to floor,vent ,and ect.The actuator motor that does not respond,is the one that is faulty.Check the ones that are accessable first,then if they all seem to work,then you may have to remove the dash to access the one that is faulty,removing the dash and allowing it to set back in the seats,so the actuator motor can be replaced.But the one you describe,should be on the bottom,hopefully.This year,I am not sure about,but I believe it is on the bottom,just remove the bottom cover under the dash and locate the actuator motor,and see if it responds to all selections,this will tell you if it is the one you are looking for,if it does not respond to temp selection,or recirculation button,or max air,then it will be the one.

    There is two,or maybe three,but not sure on this model,but it most likely is the one,when you remove it,manually move the door,and it will tell you real quick,if it is the right one,But most likely is the right one if it is not moving on any selection.

Why does My thermostat Not switch between ac,heat,defrost . there's cold air coming out of vents but not cold enough to be ac. Initially when this started the ac was blowing hot air

If the air flow cannot be controlled from vent/defrost/floor you may have a blend door issue. This is an electric motor that operates a door in the heating system to control airflow. There are usually 3 motors controlling airflow direction,heat and recirculation. The Ac not blowing cold may also be another problem. If the AC is operational, the compressor will be engaged and the Ac low pressure line under the hood will bw cold. If this is all ok then a blend door issue should be suspected

How do i fix the heater in my 2001 jeep grand cherokee

If the heater hoses are hot, the problem may be a faulty blend door under the dash. The blend doors direct air thru the heater core and the vents.

Why is my jeep stuck on defrost?

you have to check vacuum canister and vacuum lines. when a vacum line is cracked or canister has a crack you cant control air directing doors in hvac system, becasue engine creates vacuum and this canister is connected to vacuum lines and you can only control hvac system when vacuum exist on electric panel equipped Ac systems, you do not need vacuum to control blending doors. there are electric motors.

Everything works on a/c but only have def. no dash vents

There is a blend door that regulates where the air will come out of depending on where you set it on . Sometimes this blend door is operated on vacume from under the hood in the engine compartment if this vacume line breaks or is broken then you will have the problem you just described.Check for a broken vacume line. If the blend door is electrically operated check to see that you have voltage to the blend door motor if you have voltage then chances are the motor is bad and needs to be replaced also check the gears to the blend door most are plastic and some tend to strip. The blend door is located inside under the dash it may have a vacume line connected to it or a electrically operated motor but it should be located on the air duct some where you just have to look and know what your looking for. If you do locate it you can always move it manually with your hand to know that this is where the problem is at good luck and hope I helped you.

Hi There I have1994 jeep Grand Cher. cold air on heater, but hot cooland going thro core.The vacum sounds ok switching all directions : windchil , flor, mix up and down. but maybe the vacum is a bit to...

Hi, the blend door is not vacuum operated; however the veater water control valve is. Check to make sure the heater control valve (see pic below) is opening (vacuum motor should turn valve lever). If that's good, check the adjustment of the blend door cable. Make sure the door opens fully when the temp is set to hot. Please let me know if you have questions, and thanks for using FixYa.

Air not blowing out of vents

Most vehicles today have what is called a blend door and motor in the heater box. The blend door motor comes on when you select a setting. It actuates the blend door and directs the floe of air to the proper place. Sometimes the blend door gets stuck from debris that falls down through the vents. Also it is possible that the blend door motor is bad or simply came unplugged. Some of these motors are powered by electric automotive current and some are powered by vacum hoses. It is possible for the vacum hoses to break or become unplugged. Check all these options. One of my kids dropped a comb down my upper vent and it blocked the blend door from directing the air flow. That was an easy fix and I hope yours is a simple. I hope this helped you. Roger

2001 jeep grand cherokee wont blow air through vents

there is a flap to redirect the air flow under the dash, it may be an item like a pen :) that has dropped down the vent opening stopping it from moving to redirect the air ... failing that, one of the motors/cables that operate the flap has failed

2001 Aztek blowing cold air (strong) on left side of the car.

This is a blend door problem, this door diverts air either throgh the heater core or the AC accumulator core, it either provides hot, cold or a mixture or blend, this door is deep in the dash and in most cases the dash must be removed to service the little electric motor that operated the door.
