SOURCE: air condition/heater
sounds like the air-conditioning expansion valve is probably not working correctly here is a way you can fix your air conditioning:

There is only one A/C system split into 2 zones. Check the blend door actuator, it may have failed in one position or something may be jamming it. Also check the control panel in the dash, My 98 yukon did the same thing, no matter what temp you selected for the front it would blow at about 70 degrees. There is a circuit board in the control panel that gets corroded and one of the circuits controls blend door operations. Have a look.

will the air flow switch from floor to the mid to defrost? if so then we have a problem with the tempature door actuator. easy to replace just in tight place. Keep me posted for more help or if this was any help thanks

So I am the original owner of 2000 Eclipse and have taken it back to the dealer for the 1st 5 years and they would replace a hose and tell me that there was a leak and the coolant was low. Oddly enough I never witnessed leak or saw any a/f on the drive. Plus the overflow is still at full. I fed up with the dealer(warranty ran out) so I must do this on my own or suffer the arctic Cleveland commutes to work. My driveway slopes down and typically the car is parked nose down the drive. By luck I parked it bassackward or Nose Up. and had heat when the card idled in the drive. The Heater hoses are at the highest part of the cooling system and any deficiency in the coolant level replaces hot water with cold air in the heater core. I still can't tell you where my coolant goes each and every year nor do I understand why it won't **** it out of my overflow bottle when low. I just top off radiator frequently and alls well.
