cooling system

Help! I just inherited a 2003 Jeep Liberty Sport 3.7L and my ac won’t blow cold and the radiator fan won’t cut on anymore. I just replaced the fan last week because the old one stopped working and the new fan worked until today when it stopped entirely.

Hello everyone, new to the group! First time Jeep owner 196k & still running. Replaced the radiator & t-stat a few weeks ago; water pump & hoses are still new. I hear swishing from inside the heater core. Is it a stubborn air pocket?
