The vacuum hose may have fallen off cruise control Servo Unit. It’s located in the engine compartment on the driver’s side right under the breather hose that leads into the intake.
Have you checked for trouble codes in diagnostic mode?
To enter diagnostic mode:
1. Turn ignition "ON."
2. Depress the "OFF" and "WARMER" buttons on the Climate Control Center (CCC) simultaneously and hold until the segment check appears on the Instrument Panel Cluster (IPC).
Use the link below to find out what the codes mean:

Feel free to post codes.
I believe your Deville is equipped with the OBD-I system that will allow you to read codes as described above. If not, you may need a code reader.
