99 ford ranger 4cyl ac smell in cab

[Yourt16]

I had my ac gone through about 2 months ago. New compressor flushed all that, and today I go to turn my ac on and getting a bad smell coming from the vents. Almost like the pag oil. The ac is not blowing cold anymore. I noticed yesterday it wasn't as cold. Any help would be greatly appreciated! Thank you

Sounds like the evap is leaking.

I don't see any leaks? :/

I just noticed there is 2 tiny holes going from the compressor going to the condenser would that make the ac smell bad inside the cab?

You can see inside the evap box? Impressive.

I don't really understand this part, but no. Compressor and condenser are both under the hood, won't make a stink in the cab.

it might, depending on how much 134 is leaking out... if it gets pulled in through the outside air inlet.

I'd guess there's also a leak in the EVAP box.

It won't. The smell of refrigerant isn't that strong and since it is a gas well below room temp at 14.7 PSI an underhood leak that takes any amount of time to discharge the whole system will be too weak to smell in the cab. A large leak that lets out enough to smell will blow out the whole charge so quick that you never smell it, you just drive through the cloud.

I don't know what your AC qualification are, but I do this for a living, I have never found a vehicle with the smell of refrigerant in the cabin that didn't have an evap core leak.
