Question about Jeep Cherokee

1 Answer

My '96 Cherokee AC vent door is stuck in 1 position. At times it clunks & air actually blows out where I have it selected to blow. Is it a cable problem or broken blend door? If the blend door, can I repair it myself by removing glove compartment door & cutting hole into HVAC to replace the door? I'm a handy female with limited funds. Thanks.

    After this discussion, I believe I should take it to a shop for repair. Thanks for the heads up on possible cost.

Usually it's a blend door problem that is actuated by vacuum tubes. If you remove the radio and heater control panel and possibly the dash, then you can get at it:

  1. Disconnect the battery ground.

    I'm not THAT handy... to remove the entire dash etc. Can't do that. How's my shortcut idea?

    The problem with cutting into the hvac is that it might hit the evaporator which is the cold coil and other vital things are behind there, as you can see by the diagram.



    I would rather use a socket on a screwdriver to remove panels one by one until you get at the door.



    It can be deep in there, that's why it takes a professional 4 to 8 to even 12 hours to do the job.



  • chucknjo2 Jul 30, 2010

    I see your point. Is it possible to check if vacuum tube is the problem without removing lots of stuff to get at the blend door? Or does the loud clunk noise which then yields great blowing more a sign of the door as the problem?

  • Duane Wong
    Duane Wong Jul 30, 2010

    Usually the door itself is ok, it's the vacuum motor that is clunking, going back and forth arbitrarily.



    The vacuum motor is made of a rubber diaphragm that can go bad. The plastic door is made pretty sturdily.

  • chucknjo2 Jul 30, 2010

    Ok, so how do i check or fix the vacuum motor. What's a typical cost to do so?

  • Duane Wong
    Duane Wong Jul 30, 2010

    The temperature control assembly is like .5 hours according to my online resource.

    But, I could not find the vacuum motor specifically on the list of things to do to the 1996

    Cherokee, but that doesn't mean it can't be done.



    The AC control module was another .5 hours. That sounds like it could be related

    to the door going haywire.



    If the shop charges $70 per hour, it could be that plus parts.

2002 ford explorer AC and heat blowing in dash, but very weak from the vents


On the motorcraft parts web site, you can blow up
a picture of the HVAC Blend Door Motors & locations,
as well as part numbers

You can get failed motor from Amazon

With knowing where the motors are located, try switching
the air flow modes manually, to see what positions do not work

Then you know what motors to replace

I also have professional scan tool software & can see the codes
for the motors in enhanced data.

I have a 2001 jeep grand cherokee laredo the problem i have is when i cut my heat on it blows out of all vents but it is not very hot. the temp gauge is reading between 195 and 210. i felt the heater hoses...


Check that the Heater / AC Door Actuator Motor is actually functioning by selecting heat to vent and listen.

Make sure you have vacuum to your climate controls by selecting various air vents (upper/lower/face)

If the return heater hose is not warm also - then your heater core might be plugged up. A replacement heater core runs between $83 and $153 at NAPA depending on their mood when you price it. It is kind of a pain to replace you might want to have a shop do it.

A vacuum hose that controls the little door that switches where the air blows from is off, its gonna be a real chore the find which one and take the dash out to get to it, but you might get lucky and be able to look underneath the dash from the passenger side and actually see it, good luck

My ac only blows cold air out the driver side vents. The passenger vents and the rear seat vents just blow air.


There is a "blend" door on some models with automatic climate control and/or dual zone heat and air. If your model has this option, this might be the source of your problem. Possibly the blend door is stuck and can be freed easily if you're lucky. I have heard of some repairs for this problem to be quite costly, so definitely check around and get several diagnoses from reputable sources before jumping into this.

Jeep AC blows cold air at defrost and feet but not through vents


There is a flap that directs the air. the flap is controlled by a vacuum actuator. This is located inside the venting. The actuator is connected to little vacuum hoses that attach to the temperature control switch. Either the flap is stuck, or the actuator has gone bad.

Air flow selector


Your mode door is controlled by vacuum check the vacuum hose on the left side of the intake manifold. these some times fall off leaving your mode door with no vacuum and the default position of the mod door is defrost.
