Air Conditioning problem
2003 Jeep Liberty V8 Two Wheel Drive Automatic 50.000 miles

I have a liquid, clear, non evaporating, coming from the hose protruding from the fire wall passenger side. What is it? How can I correct this?

Sounds like the a/c vent drain tube. Condesation build up and runs off the evapoator core. This is normal and let it be.

2004 Jeep Liberty air conditioning question. Compressor replaced last fall and ran cold. Compressor clutch not engaging now. Have used jump wire on low pressure switch and still didn't kick in. Applied separate 12 volt source to pigtail that sits on top of compressor and clutch engages that way. Engine compartment AC fuse is ok, Driver compartment AC fuse is ok. Why isn't the system delivering power to compressor clutch on its own?

Hi
have you verified that the a/c fan is working when you, turn your ac on, and does it stay on for a good amount of time, or does it cycle off and on, also, does the compressor clutch cycle off and on frequently while the a/c is on?

It has a 3 wire, 5v reference pressure switch that gives the PCM exact pressures for it to make decisions. The A/C clutch relay is powered by the fuel pump relay.

My wifes Liberty's AC will work fine when you first start the vehicle. Then, after driving about 10-15 minutes, the ac blows warm air (non air conditioned). Intermittently, while driving at highway speeds (60+) the ac occasionally will come to life, and start blowing cold air. This usually only lasts several minutes before losing its cold air. I have checked/replaced the clutch compressor relay without any change. A friend suggested replacing the radiator fan module. Does this sound like a viable solution? Do you have any idea what might be causing the problem? Thank You!

First thing ie refrigerant check! If it's low the compressor is cycling on and off too much, or if freon is too low it's not cycling at all. If the charge is ok, check the high and low pressure switches.
