I have used search but can't find what I am looking for.

Can anyone fill me in on the common spots that the AC system will leak?

Here is where I have looked using UV Dye and UV light.

Under hood lines including front expansion valve on firewall
Compressor
Lines underbody running to Rear AC

Any help would be appreciated.

 

Under dash near heater core.
Inside plastic covered area at rear air blower (where ever there is a blower, there is an evaporator coil).
AC condenser and lines (the front radiator).
