why does my Honda Accord’s air conditioning keep turning off

Solution

1. Preparation

• Gather tools and parts needed for the repair.
• Disconnect the vehicle's battery to ensure safety while working with electrical components.
• Ensure the engine is off and cool before starting work.

2. Recharge Refrigerant

• Tools Required: Refrigerant gauge, refrigerant canister
• Sub-steps:
  1. Connect the low-pressure side of the refrigerant gauge to the A/C service port.
  2. Start the engine and turn the A/C to the maximum setting.
  3. Check the reading on the gauge; if low, add refrigerant according to the manufacturer's specifications.
  4. Monitor the gauge to ensure the proper amount of refrigerant is added.

3. Inspect A/C Compressor

• Tools Required: Socket set, torque wrench
• Sub-steps:
  1. Remove any covers obstructing access to the A/C compressor.
  2. Visually inspect the compressor for leaks, damage, or unusual noises.
  3. If the compressor is defective, remove it by unbolting the mounting brackets and disconnecting the electrical connector and refrigerant lines.
  4. Install the new compressor by reversing the removal process and ensuring proper torque specifications on bolts.

4. Check Electrical Components

• Tools Required: Multimeter
• Sub-steps:
  1. Use a multimeter to test the A/C clutch relay and fuse, replacing any that are faulty.
  2. Inspect wiring harnesses for signs of wear or damage; repair or replace as necessary.
  3. Reconnect the battery and start the engine to test if the A/C compressor engages.

5. Replace Cabin Air Filter

• Sub-steps:
  1. Locate the cabin air filter compartment, usually behind the glove box.
  2. Remove the old filter and inspect for dirt and debris.
  3. Install a new cabin air filter, ensuring it is oriented correctly according to airflow direction.
