Quest rear a/c

Power seat and remote mirrors are wired 'always hot'. Why aren't power windows wired so there is power to them at all times? What, non of these marketing/engineer types ever removed the key, started to get out only to discover they forget to roll the windows up?? Now, before someone says that since these are high current devices that could/would draw down a battery or cause the motor to overheat and burnout or cause a fire if any of those switches 'stuck' or shorted out; the same could be said about the power seat (both circuits are on a 25 amp fuse). It wouldn't be hard to design a safety timer circuit where if it senses a 'held' switch for more than x seconds, it would remove power from that circuit. The only other thing I could think of is some unknown issue with kids in the car, but if you aren't there and neither is the key, why are they? Enlighten me please.

I have a 2002 Jeep GC Limited. My vehicle has dual independent climate control (one for the driver and one for the passenger). For no apparent reason, the heater has malfunctioned. The A/C system works fine for all vents. Regardless of temperature settings, when the heater is turned on, only the driver’s side vent and the 2 vents in the center panel area blows out hot air; the two passenger side a/c & heater vents are blowing cold air. I am wondering is this a major problem that I should take to the dealer to fix. I reviewed the owner’s manual and a Mopar Jeep manual. However, the books do not seem to address this issue. I searched and located a Jan. 2005 post with the same problem; however, I did not determine the actual cause, remedies suggested (1 was given by the moderator I recall) and whether Dpatel resolved his 1999 Jeep GC heater problem. Your thoughts as to the cause and possible remedies for my malfunctioning heater are greatly appreciated. Chuck.
