When I switch from defrost vent to dash vent it stays blowing through the defrost. Any thoughts?

The climate control system has lost vacuum. When this happens it defaults to defrost for safety reasons. Look for a disconnected or broken vacuum hose going from the top of the engine through the firewall and into the passenger's compartment. HTH. -Jim
