Q: AC leak on 1996 Dodge Ram 1500

Rookie cbe0621eac06868b3efe0d8d1d3611e23c60d3114864ea2ec19a68cfbd3eebab
Has an ac leak I can't find. Can it be leaking in the fire wall or somewhere not so obvious? The compressor and fan work just has a leak I can't find.

You could have a very small leak that is hard to detect. This is why technicians use a fluorescent dye with the refrigerant oil, then as the refrigerant leaks out, it leaves a trace of the dye that can be detected with a black light.
If the evaporator is leaking, since it is buried inside the dashboard, it can be very hard to detect.
How fast is it leaking?
The slow leak on my Dodge was from the fill conection. Use the very high tech way of testing it by putting some spit over the opening and see if it bubbles up.
