PROBLEMS RE AC IN

2000 GMC Safari

I have a GMC Safari AWD 4.3 L made in 2000. Recently my air started blowing a little warm so I bought freon r134-a to charge it. That worked fine for a bit then started blowing hot air, the compressor still kicks on & off. What do I need to start troubleshooting first to determine the problem? Thanks

Sounds like you possibly have a leak when you add the charge did you also add dye?When ever I charge a ac system I always put dye just in case I have to track a leak down.
