Ok so I have this a/c problem. I filled up the compressor with about 2 cans and it got me all the freon that i needed. But when I turned off the car to go back in to the house, I hear a leak coming from behind the dash. So if someone can help me figure out where/what can it be?

given the myriad of plumbing in the dash and that most of that pplumbing stays leak free, how exactly do you expect us to help you diagnose with such vague information?

go get some UV AC dye and a UV flashllight and start hunting. or hire an AC shop. venting coolant to the atmosphere is a federal offense.

I was just asking if there is a/c lines behind the dash where POSSIBLY the leak come from.

The evaporator cooler is located behind & below the glove box. MTL that's your bad actor.
