Symptoms indicates the control panel is likely to be faulty. Check to see if you have any trouble codes. Let me know how it goes
Dual Automatic Temperature Control Module - Retrieve Continuous DTCs
The DATC module will retrieve only continuous (intermittent) DTCs when carrying out this procedure.
Retrieval of continuous DTCs can be initiated after cycling the ignition switch from OFF to ON. Normal operation of the climate control system stops when retrieving continuous DTCs.
To retrieve continuous DTCs press the OFF and PANEL buttons simultaneously and release, then press the AUTO button within two seconds. All vacuum fluorescent segments will be displayed if there are no continuous DTCs present. Continuous DTCs are indicated by the presence of the degrees Celsius symbol (°C) on the DATC module display. Record all DTCs displayed.
If any DTCs appear, carry out the diagnostic procedure.
To exit and RETAIN all continuous DTCs, press any button EXCEPT
DEFROST. The DATC module will exit the retrieve continuous DTCs mode and retain all continuous DTCs.
To exit and CLEAR all continuous DTCs, press the DEFROST button. The
DATC module will exit the retrieve continuous DTCs mode and all continuous DTCs will be cleared.
Always exit the procedure before powering the system down (system turned OFF). Once the procedure is exited the ignition switch must remain ON for at least 30 seconds to allow the temperature blend door actuators to automatically recalibrate.
Continuous DTCs will be deleted after 80 ignition switch ON cycles after the intermittent fault occurs.
