After reviewing some of the post on this site regarding the liberty I feel pretty lucky. I have now had my liberty for 8 years took it with 18 miles and now going on 96,000 miles. I have not had major issues with the car. The major problem i have right now is that I am getting a large amount of water puddling on the front passenger seat. It is not from Rain or outside intrusion. I believe it is my A/C draining inside the car. Any advise. My front carpet is soaked. I agree with many of the symptoms describes with this model. For my these problems started after the warranty period on the car. My liberty has this false contact that i could be cruising down the road specially when i break and the cabin lights flickers. Also i have experience both my rear window have fallen and do not operate anymore. I just fixed a U-bolt on the guide track an permenatly fixed them in the closed position.

I have just discovered a puddle of water on the driver side floor board of our '06 Jeep liberty. We have had this car for two years with no problems up to this point. Car has a sunroof, but seats are bone dry. Any thoughts? Any feedback will be appreciated.

I love my Jeep Liberty but it has now about 93,000 miles and starting to give all kinds of problems. The A/C works fine for a while then it stops and starts blowing hot air. It would go away if you turn it off for a while and then back on. Also, the engine light is on and the mechanic (a good one) could not figure out why. |

| 2005 Jeep Liberty... I have water dripping out but not running A/C. Any idea what this is? I am novice of auto repair but believe the is the AC over flow/runoff. Again, not running AC though... any ideas will help before I head for repair shop. Thanks! | |

Hi. Here is a quick rundown before I get into my issue. This is a 2003 Jeep Liberty, A/C compressor went (the clutch froze up) broke the belt, etc. had it replaced by a local service place. A/C, however, is not working. The compressor clutch does not seem to be engaging. If I throw 12v directly to the compressor, it will engage the clutch. If I throw 12v to the relay at the fuse/relay box under the hood, it will engage the clutch. I tried pulling the low-pressure sensor plug at the can by the passenger firewall, jumping wires together, nothing. Also just replaced the high-pressure sensor (on the a/c line by the compressor), still nothing. Fuses are good, relay in underhood fuse box is good. What i did notice it the blower resistor (behind the glovebox) is probably bad (position 1 & 2, blower does not come on, position 3&4 blower does come on). If the blower motor resistor is bad, will that cause the a/c compressor clutch to not not engage properly? Shouldnt the a/c still work in Positioin 3&4, since the blower is kicking on? Also like to add, I had a guy I know hook it up to DRB-3 at a Jeep dealer and there are no codes to troubleshoot with. Any help is appreciated. Thanks

Replying to: lj1sb (May 13, 2009 5:31 pm) When the engine is warm, running and belt is in place: -If you set the blower to position '3', does the A/C come on? With a 'warm' engine stopped and serpentine belt removed: -Can you turn the compressor by hand if you activate the clutch with jumpers? To 'break the belt' or 'freeze the clutch' could mean there was excessive effort coming from the compressor: -Is the cabin evaporator/heat_exchanger clean? (it could be clogged). If the compressor sees liquid instead of gas it will block and the pulley will immediately throw the belt off it's normal path because the clutch won't let go until the temperature setpoint has not been achieved. There should not be any engine malfunction code in case an accessory fails and the clutch is part of the compressor, it is not related to the engine. Good luck  -

Replying to: caribou1 (May 14, 2009 1:25 am) What is the cabin evaporator/heat exchanger? Where is it located? And can I do a visual inspection or test on it to determine if it is the culprit? What about my other question...the blower resistor appears to be faulty as the blower only comes on in Position 3&4....will this also prevent tthe A/C from coming on, even in Position 3&4?

Replying to: lj1sb (May 14, 2009 5:08 am) The evaporator is the heat exchanger that cools air in the cabin. On mine it's above the passenger's feet, just behind our miniature glove box  If you have pollen or leaves accumulated against the evaporator, there might not be enough air flowing through to evaporate all of the A/C liquid. This could be enough to block the compressor because you can compress gas but not liquid. Our A/C compressor pumps gas, then gas becomes liquid while flowing through the condenser/chiller located in front of the radiator. This liquefied gas will later evaporate when confronted to the warmer cabin temperature; at this stage ONLY gas must return to the compressor for another cycle... I don't think of any relation between the resistor positions and the A/C? |
