my Honda Accord AC blows hot air what could be the issue

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 to ensure safety when working on electrical components.

2. Recharge the A/C System

• Connect the manifold gauge set to the A/C service ports.
• If low on refrigerant, add the appropriate type (usually R-134a) as specified in the owner's manual.
  • Turn on the A/C system to the maximum setting.
  • Monitor the pressure readings; they should be within the manufacturer's specified range.
• Disconnect the gauges after recharging.

3. Replace A/C Compressor (if faulty)

• Remove the serpentine belt from the A/C compressor.
• Disconnect the electrical connector from the A/C compressor clutch.
• Remove the refrigerant lines from the compressor (ensure the system is fully evacuated).
• Unbolt the compressor from the mounting brackets and remove it.
• Install the new A/C compressor by reversing the removal steps and torque bolts to specified values.
• Reconnect the refrigerant lines and electrical connectors.

4. Replace Cabin Air Filter (if necessary)

• Open the glove compartment and unfasten any stops to allow it to fully open.
• Locate the cabin air filter cover and remove it.
• Replace the old filter with a new one, ensuring the airflow direction is correct.
• Reassemble the glove compartment.

5. Finalize

• Reconnect the battery.
• Start the vehicle and turn on the A/C to check for proper operation.
