Check behind the rf bumper area, you will find a vacuum resovour, check to see if there is any cracks in the lines/hose, and make sure it is connected securely. also make sure the vacuum line going into the firewall to the heater box is ok..i have had the plastic line break due to heat and age---hope this helped you !!

98 Jeep Cherokee 6cyl - heater & a/c only blow out defroster duct


Usually a sign of a vac leak between the engine and the control on the dash or the blend door.
The defrost position is the default when there is a problem with the system so that the windshield stays clear in wintertime.

'98 Jeep Grand Cherokee - My Heat/AC worked intermittently for a few days and now blows only heat. Changing the Heat/AC settings doesn't change the temperature at all. It blows very hot. AC is still...


The control for the AC/Heater door isn't working. To have AC the door has to close so that the hot air is not being blown into the car. When this door is closed it allows the cool air to pass through. This is either controled by vacuum or a ele. switch
