The white vacuum line for my blend door has been cut and is only a few inches long. No signs of the rest or where it originally was routed. Where does it lead?

 

Goes through the firewall to a connector that is either under the dash on the passenger side or in the kick panel, can't remember off hand. Easiest way to find it is to start at the climate control and follow the lines going towards the passenger door.

 

look at the bundle of lines passing right by that area, that white vacuum line busts off right where it comes out. usually comes out of the bottom of the harness..usually just have to strip the harness back a tad and find good vacuum line to splice onto..
