how to fix air conditioning not blowing cold in Renault Clio V (2019-Present)

Solution

1. Preparation

• Tools Required: Safety glasses, gloves, OBD-II scanner, refrigerant gauge, leak detection kit.
• Make sure the vehicle is parked on a level surface and the engine is cool. Disconnect the battery to ensure safety while working on electrical components.

2. Recharge Refrigerant

• Sub-steps:
  1. Connect the refrigerant gauge to the low-pressure service port.
  2. Check the gauge reading; if it is below 30 psi (or manufacturer's specified range), a recharge is necessary.
  3. Slowly add the appropriate refrigerant (R134a or R1234yf, depending on system specifications) until the correct pressure is reached.
  4. Monitor the high-pressure gauge during charging to prevent overcharging.

3. Inspect and Replace the AC Compressor

• Sub-steps:
  1. If the compressor is not engaging, disconnect the electrical connector and check for power with a multimeter.
  2. If no power is present, trace back the wiring to locate the fault or replace the AC relay if faulty.
  3. If the compressor is faulty, remove the serpentine belt and unbolt the compressor from its mount.
  4. Install the new compressor, ensuring all gaskets are replaced to prevent leaks.
  5. Reconnect the electrical connector and serpentine belt.

4. Replace Cabin Air Filter

• Sub-steps:
  1. Locate the cabin air filter housing, usually found behind the glove compartment.
  2. Remove the glove compartment to access the filter.
  3. Take out the old filter and insert a new one, ensuring the airflow direction is correct.
  4. Reassemble the glove compartment.
