Basically there is only one way to find these leaks and that is to put dye in the system and then find where it is coming out.

Here are some guides that will help with step by step instructions on how to do this:

Also, if you have not inspect the evaporator in the HVAC housing then that is where I would start based on how you have done. This is clearly not a visible component as it is in near the heater core but I bet that is where the leak is.

Let us know if you have questions on this. Thanks
