Hi,
I replaced my vacuum lines to the 4x4 switch on the firewall and the HVAC controls. I was pulling on the 3rd line (located on T shared with the above 2 lines. The hose let go, but from down by the drivers fender. The line appears to be about 6" long and I can't find the location it came from? I have plugged the line off from the T as I needed to drive the vehicle. Just wondering if the hose is part of the cruise control? Not sure if 2000 Jimmy 4x4... 4.3L uses a vacuum, or is it all electric? That damn short vacuum line has got me stumped.
Thanks
