Solution

1. Preparation

Gather tools and parts necessary for repair.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery to ensure safety during electrical work.

2. Refrigerant Recharge

Check Refrigerant Levels
- Connect the manifold gauge set to the low and high-pressure service ports.
- Read the pressure values to determine if the system is undercharged or overcharged.
Add Refrigerant (if low)
- If the refrigerant is low, connect a refrigerant canister to the low-pressure port.
- Open the valve slowly while monitoring the gauge until the proper level is reached (typically around 30-40 psi for low pressure).
- Ensure to use the correct refrigerant type (usually R134a for Clio V).

3. AC Compressor Inspection

Inspect the AC Compressor
- Examine the compressor visually for any signs of wear or damage.
- Check the electrical connections and wiring for wear, corrosion, or loose connections.
Test the AC Compressor Engagement
- Reconnect the battery and turn on the AC system.
- Observe if the AC compressor engages. If not, further testing of the relay and fuses is necessary.

4. Replace the Cabin Air Filter

Locate the Cabin Air Filter
- Access the cabin air filter compartment (usually behind the glove box).
Remove and Replace the Filter
- Remove the old filter and install a new one, ensuring proper orientation.
- Close the compartment securely.
