Find outlet selection motor (between accelerator & HVAC case). With ignition "off" unplug connector from motor, after 30 second lapse reconnect. Turn ignition switch "on", observe white gear & linkage for smooth motion. Smooth motion: You're in luck. No motion: GENTLY rotate white gear by hand. If motion begins; lube linkage with lithium grease. If still no motion: remove HVAC control head, unplug connector & clean circuit board connector strip. Reconnect & Retry. Lastly, outlet selection motor may have failed, requiring its R&R (lotsa fun!).

It's most likely a vacuum line, look
under your hood (close to the cowl panel) for a disconnected, cracked
or broken vacuum line.
In some rear cases, it could be the
vacuum switch (in dash). Or vacuum diaphragm (under dash).
Hope this helps you ???
