Same thing with my 964.
Spent over $1K to try and resolve it.
The mechanic had the entire HVAC system apart.
No solution to date.
I guess it is one of the little joys of the 964.

I had the exact same problem on my 89 C4 and i found the heater tubes in the right and left kick panels were leaking just enough to make a whistle type noise. tightened up the hose clamp and noise is gone.
