987.1 Climate Control Unit to 987.2
Hi everyone, this is my first post, but I've been lurking around 
since 2014.
I was wondering if anyone with a 987.1 has swap their climate control unit with a 987.2 unit? If so, is it a simple plug-n-play or will there be some modifications required?
Or will it not work at all?
Thanks in advance.

This is basically impossible to do. Try a search on one of the other forums (6speedonline, maybe?) as it has been discussed there.
Basically, you have to use the HVAC module from a 2009 997 Turbo only. IIRC, you also have to have the system coded and perhaps even wire in a diode/resistor along the way. The issue is the difference in the PCM version between the models and the way it controls the internals.
I had considered this on my 05 997, but proved too difficult/expensive to have done.
