Q: Neon colored leak in rear of vehicle on 2005 Chevrolet Uplander

Rookie cbe0621eac06868b3efe0d8d1d3611e23c60d3114864ea2ec19a68cfbd3eebab
I have something neon colored leaking under rear end of my Uplander. Any suggestions of what this could be?

You have both antifreeze and R-134 going to the rear heat/cooling unit. The R-134 will have a neon colored leak detector in it. Or if the antifreeze is not the original DexCool, it could be green color also. The leakwould be on the driver's side, just behind the rear wheel.
