    Defrost is the default setting.. for a Vacuum failure. Check the fuse that controls the Vacuum Pump, then check the Vac line from the Vac pump/accumulator.. to the manifold located behind and to the left of the Glove box... for leaks and good connections.

    4X4 ? check/inspect the vac lines at the front Hubs.

    Welcome to SDD. Check vacuum hoses for cracks as well.
