I have a 1998 XL 5.4L 4WD (original owner) with rear AC and the AC in the front vents is ice cold but the AC from the rear vents is now blowing warm. No combination of vent and temperature control knob changes will get cold air out the rear vents. Note - the air from the rear vents will get much hotter if the temperature knob is turned to hot so it appears to work for the hot setting.
