#1 recheck the connection on the plug. Make sure now wires pushed back when you installed the switch.

#2 You have either a broken/disconnected vacuum line under the hood or a bad selector switch. Look at all of the small, black palstic tuning under the hood. Especially in the firewall area. This controls the HVAC vacuum.
