Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery for safety.

2. Check Refrigerant Level

Connect the A/C manifold gauge set to the service ports on the A/C system.
Verify the pressure readings against the manufacturer's specifications.
If the refrigerant is low, proceed to recharge the system.

3. Recharge A/C System

Use a proper refrigerant identified for the Renault Clio V, typically R134a or R1234yf.
Follow the manufacturer’s guidelines for the correct amount of refrigerant to add.
After recharging, run the A/C system to check for proper operation.

4. Inspect and Replace Cabin Air Filter

Locate the cabin air filter compartment, usually behind the glove box.
Remove the glove box to access the filter.
Inspect the filter for dirt or blockages; replace it if necessary with a new one.

5. Test A/C Compressor and Relay

Reconnect the battery and start the engine.
Turn on the A/C and observe if the compressor is engaging.
If it does not engage, check the A/C relay and fuse; replace if faulty.
