hi out there.
posting this after extensive searching of this site and others.
helping a friend whos xterra is not moving air out of any but the face and foot vents, regardless of the position on the dial indicator.
i notice through searching that the control head housing the 3 dials etc is a troubled part, but in reference to a/c cycling unlike this case.
looking for further insight. admittedly not an xterra owner. i have several early quattros and have dealt with flap motor/servo failure and broken linkage as well, which maybe this could be? so before i go and start dismantling my friends dashboard i figured a post was worthy for added insight with hopes someone has had a similar issue.
again, -the only air moving through the vents is coming from the face&footwells. regardless of dial position.
if you can help, thanks //brian
