SOURCE: 2004 Ford Crown Victoria no air flow through main air vents

Chances are the electronic/digital HVAC control unit is bad. This same problem happened to me and I had to replace the entire unit. The dealer wanted to charge $800 for just the part! After I freaked out on them, they found a used one for less than half. Sorry, but there's no easy fix here.

SOURCE: 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.

SOURCE: WILL NOT SWITCH AIR FLOW STUCK IN DEFORST VENT

when your car is in defrost it has an ac cycling it removes the moisture then sends the air over the heater core depending on how warm you set it you can feel warm or cold but the ac is always cycling...ridding the moisture...you need a good ac tech it will be okay...its just expensive going into the heater core if needed...!

SOURCE: Heater and Air conditioner work bur air flows from

There may be a couple of items to look at here.... but the most common problem is a source of vacumn to the pneumatic operation of the heat/a/c vent doors....if vacumn is not distributed properly to the vents you command it is assumed that there is either no vacumn to the selector swith panel(broken vac. line,kinked vac. line, defective in dash a/c control panel) or under the hood a defective vac./heater control valve that is stuck,frozen, not allowing the vacumn to pass through it to supply the indash pneumatic controls and/or panel.
Most vacumn systems that i have ever came in contact with incorporate a vacumn supply tank(nothing more then a round plastic vac. resevoir) which is used in sequence with the a/c heater controls, its purpose is to keep an even vacumn supply to all command points continously while the vehicle is being driven, without this supply one will experience the a/c coming from various different non selected dash vents upon acceleration, this is a direct relation to the tank either being defective(leaking vacumn) or its supply hose(usually vey tiny rubber/plastic tubes) being pinched or broken not allowing the vacumn to the supply tank.
listen for vacumn leaks(hissing sound), look for the obvious...broken vacumn lines or hoses, also check for a defective one way vacumn valve on some pneumatic controlled door vent systems(these valves are inserted in a vacumn line one side being the ""in" port and the other side of it being the "out" flow port,typically if these dont work the vents will also devert your a/c or heat all different ways through your dash.
to check these valves, simply remove from the vacumn hose, and apply vacumn to one side,if vacumn flows through the valve, apply the same vacumn to the opposite side of the plastic valve, if vacumn flows through on the opposite side the valve is bad, it should only allow flow from one side not the other. These valves are small and are usually white or black plastic and look like the old vacumn dash pots used on the old carbureated engines only smaller with one small hose in and one small hose out.

SOURCE: REPLACED BLOWER MOTOR CONTROL MODULE...Now blower

check your blower hoses to see if one or more have come loose or got redirected or the selector switch isn't functioning properly (is it blowing better on defrost as opposed to floor vents, or forward vents, etc.)
Good luck

Need cooling system diagram for 2010 jeep liberty 3.7 v6


It is electric.It is mounted in the center on top off the air plenum. You have to remove the dash to get to it. Last one I did was the heater core. 2003, had to remove the dash out of the vehicle, drop the steering column and remove the air plenum. All day job. You need a manual, lots of nuts, bolts, and screws to remove.

2010 liberty no air from center vents


blown fuse is first.
bad dampers.
or controls that control said dampers.
or a rat died in there. (nah) but.... see it.
so why not crack a book, its called the FSM. and is 100% covered there. on the HVAC chapter, all the tests are there.

or login to alldata.com and read the same chapter.

the damper motors are complex. and not 2 are the same car to car brand, so.... ONLY THE FSM works, for YOUR car.
fact. serv. man.

Air Condtioner Partially Working Jeep Liberty 2010


Usually a sign of a stuck blend door under the dash.
Could be a faulty blend door actuator, or the main controller.
You may need a shop manual to make the repairs since this is generally beyond the abilities of a DIY repair book.

Where is the blower motor relay located on a 2010 jeep liberty


on all speeds, is it dead sounding or only no air flow???
wow no symptoms posted only this goose chase deal.

use the scan tool yet? see all DTC errors.
2008 cars can report most cause of lost power etc,
not scanning, invites expensive gue$$ing.!!

HVAC 101: (
gdoes the motor have 12vdc on high? at connector to it>?
on all speed's (now that is a KEY FACT there)

  1. defeat air bag first or die , fiddling these parts.
  2. do the HVAC calibration yet? per FSM.
  3. scan it yet ,if not you will guess wrong. I promise,
  4. i have to stop my online page ,is missing the wiring sections.

calibrate damper:
Use this procedure to ensure that the A/C-heater control is correctly calibrated to the blend door actuator. If the calibration is not correct, the heating-A/C system may experience a condition where full heating or cooling capabilities cannot be obtained.

Many steps can not be done with out a real jeep scan system.
sorry, cant.

Air blend door jeep liberty 2010


My blend air door is stuck on my 2010 liberty. I have removed the actuator panel on the drivers side and the middle door that controls the air flow to the dash is completely seized. There are 4 blend air doors on this liberty, 2 control the heat/ac and 2 control the air flow.
there is no access to them from the drivers side and the passanger side looks like I have to cut into the air box to get to them.

Heater only works while accelerating


this sounds like the coolant is low and should be checked.when you accelerate the coolant flows faster through the system.when at idle or driving slow the air will accumulate at the highest point which is usually the heater core thats why when in this state you get cool or luke warm air out the vents.
