Question about Jeep Liberty

1 Answer

I have a 2008 Jeep Liberty. The heater works great still, but the air conditioning does not cool at all. It blows like it should, just no cool air coming out. Any ideas to what the problem is?

Sounds to me like your refrigerant has leaked out. The AC system is sealed and will never blow warm if it never leaks. So you will need to put some dye into the system and look for the leak. Once it has been found you will have to discharge what might be left in the system into a tank and then repair the leak. Then you will have to put it under a vacuum for at least 3 hours and this will tell you if the repair worked as well as remove all the moisture from the system. If the repair was a success then recharge the refrigerant and enjoy the cool air inside your vehicle.

The most common fault is air pockets in the cooling system.
Is the radiator full of liquid coolant ?

2002 jeep liberty heat only works at high rpm


Sounds like low flow issue. Flush and clean system, PROPERLY! Buy a flush kit, drain system, blow compressed air through, fill with cleaner/water mix, run for 30 min with heat on, drain system, blow out with compressed air, fill with water, run for 30 min, drain, blow out with compressed air, fill with 60% coolant mix.

2008 Jeep Liberty-My heater was barely warm-blowing fine tho. Was told I had a plugged heater core and needed a new one. Had a new heater core put in and then my air conditioner stopped blowing cold air....


I woild be checking the vent controls as if the ac is working and the core was blocked then the air would be cool when the heat was selected but not changing Fixing the heater has resulted in a /c not being good enough to cool the air if the vent is not properly selecting. The point is that if the vent selection is not working properly (vacuum hoses) then the 2 faults will be related.

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.

I have a 2008 Jeep Liberty. The heater/air blower just quit working, I checked the fuse and that was good. What's the problem?


most likely its the blower motor unless it has a relay that you cant check you just have to replace it. sometimes you will have a few relays that are the same and you can use one just to see if thats the problem,but make sure its not one that controls anything major.

2008 jeep liberty vents not blowing out air?


I also have an 08 liberty, but my issue is that the heat won't blow out on the floor....the air vents and defrosters work great. You can hear it trying to switch over but doesn't. You need a new Air Flap Actuator (16-$30) The real issue is that you have to take offf the whole das in order to fix it. That is abouy 9 hours worth of work.

My automatic headlights stopped working on my 2009 Jeep Liberty. I can turn them on manually.


My 2008 jeep liberty's headlights flickered when I was just driving down the road in the dark and then completely shut off on me. My fog lights are the only lights that work now and my lights continue to blink off and on a couple times and then completely off. Now that this has happened my jeep will continue to lock and unlock itself and also my blowers for heat and cool air will not blow at all...

2005 jeep liberty blows cold air through the heater.


could be the thermostat if it was just stating to go bad,could also be a vacume problem not letting the door for the ac/heat close all the way for a few min.and if its really cold out like below 35,then its going to take longer to warm up,my jeep takes like around 20 min at idle to warm up.yours could be a case of over cooling in cold weather too ie(electric fans on before it warms up)that would be the thermostatic sensor.
