Having problems with your 2002 Jeep Liberty ?
The air conditioner will blow air out but the air is not cold. What could be the problem?
Your system is low on refrigerant and needs to be checked for leaks and recharged with R134. If the system has sufficient refrigerant (base pressure of 70 - 90 lbs pressure checked with A/C gauges) then check to see if your a/c compressor clutch is engaging. If it is, then the compressor is bad. If the clutch is not engaging (you'll here it click when you turn on the a/c set to coldest setting), then you have a bad connection of the wire plug to the compressor, or a bad connection at the receiver/dryer.
Normally this is caused by a leak in the system allowing refrigerant to escape. Take it to a professional unless you have the knowledge and proper tools, and have the leak repaired and R134 added to the system. It is illegal to add refrigerant to a system with a leak without first repairing the leak.
