4 Wheel Drive/SUVs: 2000 jeep, jeep cherokee sport, vacum leaks

Question
I have a 2000 Jeep Cherokee sport. The air conditioner works but does not come out of the ducts of the dash. any help would be appreciated.Thanks

Answer
With the engine running, check for vacum leaks under the dash(listen for a hissing sound) and also under the hood. Tha diverter doors work on vacum poer and may not have the proper vacum. Also, pick up a Haynes or a Chiltons manual and this will better help you locate these lines for inspection
