I noticed my 98 blazer was not engauging the front tires so I checked out my acuator under the battery box and followed my vacuum line only to find out its broke off and hanging down. I cant seem to find what this line was hooked up to. Can somebody please help me or post a pic. Thanks.

This line either runs from the transfer case all the way to the front axle actuator or runs to a vacuum switch located on the firewall that will have another vacuum line running back to the transfer case (IIRC).

This may be a dumb question, but where on the transfer case does the vacuum line connect? Mine is just hanging down as well. Is there a diagram, or picture? I''ve reached all around the transfer case and can''t find a place for the vacuum line.

Your going to need a mirror most likely, like you would get at the parts store on a handle.

Hooks up to a switch on the top of the transfer case. Drivers side, on top. Stick your hand up there and you will feel it. Hard to see without a mirror.
