Smile Vacuum Question ?
My 2001 psd blows air through the defrost vents only. Could this be a vaccum leak or a blendor problem, any sugestions are welcomed.

If your truck is a 4x4 with auto hubs, be sure to check the vacuum lines all the way to the hubs.

Also check fuse #24 in the in cab fuse panel. It's the blend door actuator fuse.
