Jeep Liberty Heating Ventilation and A/C
I have an '03 liberty and I need to have the ac recharged. Is it worth and feasible to charge it myself with a kit from the auto parts store or is it better to take it in to have the work done? Any help would be greatly appreciated. Thanks, and Jeep on!!

Take it to a qualified shop that does auto a/c and get it diagnosed and fixed. Just a suggestion.

Only problem so far on my 03.

Tough call!
Perhaps rolling your windows down for that dreadful interim would help?

Thank you.
If you've blown your engine head gasket and have a (exhaust) gas pocket trapped in there, you may face the same symptom.
Check your antifreeze level first, and when the engine is cold try to move the cooling liquid by doing a 'massage' on your hoses. On a normal cold system you can feel and hear the liquid move back and forth once you open the filling cap. If by doing this the coolant pours out from the top reservoir, you have excessive restriction to flow through the main radiator. The pump can overcome this restriction, you can't.
Next, start the engine with the top reservoir open and wait for the thermostat to open. You should see coolant flowing into the top reservoir. This is a good way to check for air trapped in the circuit: just let the air out and refill to normal level.
On a normal cooling circuit you can open this little reservoir when it's hot and while the engine runs. It should not out gas much; the cap is made with a ramp to allow progressive release of overpressure and the tiny hose located under the cap collects the overflowing coolant.
Always keep in mind this can be hot liquid and should be disposed of as a chemical waste
Is this normal?
The dealer says yes, but the heater duct seems to have a little latch on it like it is missing an extension piece that would bring it down to the driver's feet, similar to that of the passenger side.
I also have cold air blowing on me from right up under the console by my right leg.
Can somebody else with a 2008 Liberty verify that their heater duct on the driver side is the same as mine, or is it more like that of the passenger side?
Thanks.

:confuse:
I know these vehicles aren't really the same, but they do share a similar history, and one sort of replaced the other.
Good luck!
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.
Also, the engine light is on and the mechanic (a good one) could not figure out why.
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
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

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?
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?
I don't understand where the clogged drain is located.
I found lots of dirt accumulated between the decorative plastic liners and the body, right underneath the doors. This is where bottom panels join the chassis. To remove the residue where perforation can occur, we need to replace the 'one-shot' plastic fasteners or to paint this 'vertical' area in black.
