I agree with condenser. Had dye added then used uv light to find leak on the small pipe elbow where it goes into the side. You can see it through the grill on the lower right. It will get worse and slowly stop working. if you haven't got it done yet. Changed mine myself then had it charged
Had the hiss myself. Simply put... you have a leak AND low refrigerant. The hiss is air in the system. The cool air is due to low refrigerant. For the vast majority of people this is NOT a DIY project. As it requires a recovery and vacuum system to pull the old refrigerant out. Then put everything under vacuum while properly servicing. There is a whole EPA certification just for doing this service. Frankly, you are better money spent to nut up and pay for a PROPER repair and service. (recovery systems and parting together a system from scratch will run you well over $2000 for something you'll probably only need to use once in your life.)
I have a 2020 Durango. If mine were making that hissing sound I would have mine check out. Then I can determine from there on what steps I should take next. But I hope that it gives you no further issues. I’ve been watching your videos for awhile now. And I do believe that this my first time commenting. Be safe ✌🏾
Hey, I just had this problem on my 2018 Durango too. As @emoryjaymz mentioned it was low on refrigerant due to a leaking A/C condenser (the part that looks like the radiator). The job was like $1200, but luckily I have the warranty to cover it.
On my 2013, the hissing only comes up when I put the heat on, it sounds like it’s coming from one of the vents on the passenger side. The AC blows cool but not freezing cold like you mentioned. I think there’s possibly a leak somewhere but I’ll have to look into it further.
I just replaced my condenser coil (had a small leak) this past Monday, I was experiencing the same issue, dealer wanted too much $$ and I was going to have to rent my own vehicle, I ended up grabbing all the materials and tools and did it myself for right about $330 total, hissing is gone and now I’ve cold A/C.

It's your blower motor my brother. Just a few screws and you back to normal. Your front blower motor.
I experienced this before my A/C condenser went out. I would get prepared to replace it.

Evaporator core or line going to the evaporator core. Happened to my wrangler. Will only get worse.
