WHAT WOULD CAUSE THE A/C TO COME ON AUTOMATICALLY AND NOT SHUT OFF?
2004 Lincoln Aviator • 146,000 miles
When the truck is started, the a/c comes on, and no matter what button I push (off) it stays on for approx 10 min, then I'm able to turn it off with the off button, or change the temperature. The other buttons, (air flow, defrost, ect.) buttons do not work even after the 10 minutes have passed. All I'm able to do after the 10 minutes is turn it off, or change the temperature. Also, I noticed that the A/C button seems stuck. If you press it, it doesn't return - as if the spring is broken. All of the other buttons return to its original state after pressing.

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.
