why is my Renault Clio V (2019-Present) air conditioning not working in summer

Solution

1. Preparation

• Gather tools and parts needed for the repair.
• Disconnect the vehicle's battery to ensure safety during the repair process.

2. Recharge Refrigerant

• Tools Required: Manifold gauge set, refrigerant canister (R134a), AC vacuum pump.
• Connect the manifold gauge set to the low and high-pressure service ports.
• Start the engine and turn on the AC to the maximum setting.
• Check the pressure readings; if low, proceed to vacuum the system.
• Use the AC vacuum pump to evacuate the system for 15-30 minutes to remove moisture.
• Recharge the system with the appropriate amount of refrigerant as specified in the vehicle service manual (usually around 450-600 grams for the Clio).

3. Replace Cabin Air Filter

• Tools Required: Screwdriver or trim removal tool (if required).
• Locate the cabin air filter access panel (usually behind the glove box).
• Remove the panel and extract the old cabin air filter.
• Install the new cabin air filter, ensuring the airflow direction is correct.
• Reattach the access panel securely.

4. Inspect and Replace AC Compressor (if necessary)

• Tools Required: Socket set, torque wrench, refrigerant recovery machine (if replacing compressor).
• Disconnect the AC lines from the compressor and note their positions.
• Unbolt the compressor from its mounting bracket and remove it from the engine bay.
• Install the new compressor by reversing the removal steps, ensuring to torque bolts to manufacturer specifications.
• Reconnect the AC lines and recharge the refrigerant using the steps outlined above.
