I recently filled my 2001 Jeep cherokee sport with refrigerant it blew cold air for like 10 mins then it started warming up and now it blows hot when it’s on cold. Also after I added the refrigerant it started making a noise I’ve never heard before it’s soft but noticeable. I have checked both the fans and they are working the the compressor thing spins but I have no idea if it would be the ac clutch or something else I have very little experience I don’t wanna mess with nothing until I knows can someone help ?
