This is a known issue in high humidity environs. I used to have the same problem on my old 560 SL so it isn't unique to the Z8. Here's what the repair slip of another owner's car said his dealer did....
"Remove glove box and underdash panels+vents. Water leaking at area where heater box goes into hole. No access to inspect. Remove part of heater box and upper dash. Remove blower motor to get at bottom of housing. Blow out drains w/air hose. left apart and roadtest.
Water draining through box and not leaking. Did get some water from low side pipe sweating.insulate with A/C foam. Reassemble"
This was a 5 hour job according to the work slip & he's had no subsequent problem with it.
