Re: Cooling Fan

Welcome to the garage.
Donīt know if the Liberty uses a high pressue switch, or a pressure transducer in the AC system, but that one could be faulty. It gives a feedback signal to the PCM, which in turn will cycle the compressor, depending on the pressure. The PCM will also give the signal to the cooling fan relay, to switch the cooling fan on.
