Nope. Disheartened by this failure, I gave up. lol.
I've had my car for 11 months now, and I haven't had any problems with the car taking too long to cool off (even with my Carbon Black/Black Nappa combo) or the leather drying out. The A/C is really good, I keep my Nappa (especially the dash) well-conditioned, and I make sure I always close the sunroof during the day.
Sorry I can't offer any good suggestions.
