Having problems with your 1999 Jeep Grand Cherokee ?
1999 Jeep Grand Cherokee Automatic air works but after about 10-15 minutes the air flow only comes out the floor, even though it should be out the dash vents.
Check under your hood for a vacuum leak. There is probably a broken loose or cracked line somewhere. Use a length of fuel line held to your ear, and with the engine running, listen for a hissing sound. Wiggle all the hoses around as you are listening.
