ok so i spend some money recharging my ac and i notice after i turn the car off i hear hissing from the from left side of my car for about a min or less then all of the sudden its not cold anymore in my jeep what the hell i have a 94 jeep grand cherokee limited and have no clue i dont want to add air and its not gettin cold help lol...

Hissing could be the refrigerant leaking out.

hmm well u think a sealer should work,I'ts comin from the front

The hissing sound right after you turn off the a/c is the high and low side pressures equalizing and is 100% normal. There is no place for sealers in a/c repair. If you have a leak find it and repair or replace the leaking parts Save the band-aids for minor cuts and burns and not for a/c repair.

The Hissing is normal. Reekor is right.
