Jeep Liberty 2003 A/C problem
A/C works but has been cutting out when temp is high -- i.e., System begins blowing hot air. Seems like the compressor may be disengaging(?)
As mentioned, this seems to happen only at high outside temp. If I have the A/C on at night, for example, it will continue to cool.
Any ideas as to what might be causing it. I'd like to have some idea before taking it to a mechanic and have them tell me I need a new compressor or something equally costly. TIA!

You could try to jump your cycle switch. When you feel your air begin to blow warm, pop your hood and see if the compressor clutch is engaging. If not the disconnect the connector from your cycle switch and jump the 2 terminals in the connector to see if your clutch then engages. If so you have a faulty cycle switch. You will find this switch by or on the acculator.

Or it could be your thermostatic switch in the airbox. It's a component used to engage and disengage the compressor clutch. It prevents water (condensate) from freezing on the evaporator core. It also controls the temperature of air flowing out of the evaporator fins.

Typically no, you usually hav eto lower the glovebox and it should be right behind there with a wire harness going to it.
