Our car has a parasitic battery drain that is very noticeable.
I've found a fuse, that when pulled drops the measured battery drain from ~ 140mAmps to 10mAmps.
This is repeatable.
The fuse index says it's the heating / climatronic which I take to be the HVAC control
I know that 964 / 993 CCUs Climate Control Units have this failure mode.
Have any of you seen it in a 997.2 Carrera?
140 mAmps with fan off and HVAC off.I'm uncertain how to troubleshoot the CCU
Thank you

Since I'm making this troubleshooting process up as I go along, I just;
Took the meter out of the circuit.
Connected the battery
Key on
Cycled thru all of the HVAC functions
Turned HVAC system OFF
Put the meter back in the circuit
=
No change
