June 1, 20169 yr My AC on my 96 did that. It was a vacuum line that crossed over the valve covers and got too close to the exhaust. Bob

Bob I'm guessing it's something simple like that. @stevens cummins, Pop it in 4wd and see if the 4x4 light comes on. If not, it surely has a leak or the pump is toast.
June 1, 20169 yr Author OK guys you all was right, thanks for the help. I found the vaccume line going through the fire wall inside the foam was rotted out would have never found it if it hadnt broke trying to in hook it at the elbow I pulled the line from behind the HVAC system an rann it out the drivers side of the fire wall cause I didn't have any line laying around now it works great
