Cut a half inch of rotted 3/16" rubber hose away, wrapped it in sail tape, flipped it around and re-attached my vacuum supply line to the wee little vacuum reservoir that lives under the battery in the wheel well.
It's not locked on 70%/30% defrost/floor anymore. I can now ask my passengers if they prefer a different climate, Ha!

Well, I think I have determined that the Mean Green alternator has gone soft. Won't provide proper voltage at idle... (the alternator came with the Jeep.)
2005 Red Top Optima holds +/- 12.5v cold with surface charge drained.
Checked auto belt tensioner.
Used multi-meter prior on the battery to start-up, at start-up (no head lights or heat), then with head lights & heat.
Won't hold 12v on the battery under 1200rpm. Drops below 12v at 700-800rpm until about 11.6v when the Check Gauges light comes on.
Revving the rpm's to 2000, it goes up to 14.6 volts.
Worth a trip to NAPA for their test?
FWIW- the Jeep still starts at -19C albeit took a couple of cranks. At -12C, no problem.
Traded my hard top for a soft one, no regrets so far!
I sold my hardtop and bought a supertop nx. I was worried about going through ice and snow with it this year but it has done just as good as my hardtop for noise and keeping it warm. I will be a soft top guy from now on. And so much easier to drop the top then lift it off all the time!
