Solution

1. Preparation

Gather tools such as an A/C manifold gauge set, OBD-II scanner, and basic hand tools.
Ensure the engine is off and cool before starting work.

2. Check and Recharge A/C System

Sub-steps:
1. Connect the A/C manifold gauge set to the service ports on the A/C system.
2. Read the pressure levels; if low, proceed to recharge the system.
3. Add the appropriate type and amount of refrigerant as specified in the owner's manual.
4. Disconnect the gauge set and start the A/C to check for cooling.

3. Replace Cabin Air Filter

Sub-steps:
1. Locate the cabin air filter housing, usually behind the glove compartment.
2. Remove the glove compartment to access the filter.
3. Take out the old filter and clean any debris from the housing.
4. Install the new cabin air filter, ensuring it is oriented correctly.
5. Reassemble the glove compartment.

4. Inspect and Replace Blend Door Actuator

Sub-steps:
1. Remove the necessary dashboard components to access the blend door actuator.
2. Disconnect the electrical connector and remove the actuator from its mounting.
3. Install the new actuator, ensuring it aligns correctly with the blend door.
4. Reconnect the electrical connector and reassemble the dashboard.

5. Verify A/C Compressor Operation

Sub-steps:
1. Start the engine and turn on the A/C to the maximum setting.
2. Check if the A/C compressor engages and spins.
3. If it does not activate, further diagnose the electrical supply or pressure switch issues.
