Solution

1. Preparation

Tools Required: OBD-II scanner, basic hand tools (screwdrivers, pliers)
Turn off the vehicle and disconnect the battery for safety. This will help in resetting the system without any electrical interference.

2. Resetting the AC Control Module

Locate the AC control module (usually integrated with the climate control unit).
If your model has a specific reset procedure (refer to the owner's manual), follow those instructions.
For a general reset:
1. Reconnect the battery after a few minutes of disconnection.
2. Start the vehicle and turn on the AC system to the maximum setting.
3. Cycle through all settings (fan speed, temperature, and modes) to allow the system to recalibrate.

3. Additional Steps (if required)

If the AC still does not function properly, reset the climate control settings:
1. Turn off the ignition.
2. Press and hold the "AUTO" and "OFF" buttons on the climate control panel simultaneously.
3. While holding these buttons, turn the ignition to the "ON" position (do not start the engine).
4. Continue holding the buttons for about 10 seconds until the display resets.
