I have a 2015 Suburban with no AC. The condenser was checked and is fine and there are no leaks in the system. I put some Freon in with the AC Pro kit and while the rear AC is now cold the front is still warm. I’m thinking it might need more (put about half a bottle) but is there any chance the compressor could be going? I’m thinking no because rear is now cold and I don’t believe these trucks run two systems for front and rear. Any insights on this would be great.
