why does my Renault Clio V (2019-Present) air conditioning blow hot air

Solution

1. Preparation

• Gather necessary tools and parts.
• Ensure the vehicle is parked on a level surface.
• Disconnect the battery to avoid electrical shorts during repair.

2. Recover Refrigerant

• Tools Required: A/C recovery machine
• Use the A/C recovery machine to safely remove any refrigerant from the system before performing repairs.

3. Check and Recharge Refrigerant

• Tools Required: Manifold gauge set, refrigerant
• Attach the manifold gauge set to the A/C service ports.
• Check the low and high side pressures. If pressures are below specifications, charge the system with the appropriate type and amount of refrigerant as per the manufacturer’s specifications.

4. Inspect and Replace A/C Components

• A. Inspect A/C Compressor
  • Visually inspect for any signs of wear or leaks.
  • If found defective, remove the A/C compressor by unfastening the mounting bolts and disconnecting the electrical connector and refrigerant lines.
• B. Replace Cabin Air Filter
  • Locate the cabin air filter housing, usually behind the glove box.
  • Remove the old filter and replace it with a new one, ensuring proper orientation.

5. Reconnect and Recharge

• Reconnect all components, ensuring all connections are secure.
• Use the A/C recovery machine to evacuate the system to remove moisture.
• Recharge the system with the correct refrigerant amount.

6. Test System Operation

• Reconnect the battery.
• Start the engine and turn on the A/C to verify that it is now blowing cold air.
• Monitor the A/C system for any unusual noises or leaks.
