4. Inspect 12V Battery Voltage

Use a multimeter to measure the voltage at the 12V battery terminals.
If the voltage is below 12.4V, consider charging or replacing the battery.

5. Reset the 12V Battery

Reconnect the 12V battery after confirming proper voltage.
Wait for a minute and then check if the climate control system responds.
