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.
