Does anybody know what the PCM is? Seems that I need one for my a/c to work on my Liberty.

Replying to: almaf (Feb 05, 2008 10:45 am) Not sure if you got it fixed but maybe this will help. Had the same problem with a company car (Dodge Stratus). Had it to the dealer four times then took it to a local garage. The tech at the service station found that the drain holes on the firewall and the a/c drain under the dash weren't aligned. He pulled the dash apart, aligned it and the problem was gone. Think it cost us about $200.00 in labor. Good luck.

Replying to: goslow (Feb 04, 2008 8:30 pm) Has your floor heater problem been resolved? Mine still blows cold air around my ankle on the driver's side.
#34 of 50 A/C leak by zubi305 Jan 02, 2009 (6:52 am)
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.

Replying to: zubi305 (Jan 02, 2009 6:52 am) I had the same problem with my liberty.The problem is the a/c drain as you said,the short 1/2" drain on the passenger side firewall is too short and the engine fan blows the water back and it drains down the inside of the firewall onto the passenger floor.Just get a 4" to 6" piece of heater hose and it should fit tight on the the drain and problem solved.
#36 of 50 Phantom water leak 2006 Liberty by waNugget Jan 06, 2009 (9:32 pm)
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.

#37 of 50 2003 Liberty Sport by jrivera51 Feb 10, 2009 (6:19 am)
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.
#38 of 50 Water out of tube on passenger side of firewall - Jeep Liberty 2005 by dasbooboo Mar 27, 2009 (10:58 am)
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!
#39 of 50 2003 Jeep Liberty A/C by lj1sb May 13, 2009 (5:31 pm)
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.

Replying to: lj1sb (May 13, 2009 5:31 pm) Hi, 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   - Replies to this message: lj1sb (May 14, 2009 5:08 am) caribou1 (May 14, 2009 6:42 am)
