Clutch works as it should. There is no electric fan on my liberty.There is a post here by LiberyTC on cleaning the air input slot just under the windscreen and also there is filter inside the cabin just behind the glove box that gets clogged up.
If you clean up both areas you will get better air-flow but possibly you need a recharge of refrigerant.
Observe and listen to the clutch that engages the AC compressor when at idle to see if it is dis-engaging too often or if the clutch is slipping. Also check what the electric engine cooling fan is doing.
