why is my Honda Civic 11th Generation (2022-Present) AC not blowing cold air

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 and Replace AC Fuse

• Locate the fuse box (usually under the dashboard or hood).
• Remove the cover and identify the AC fuse using the diagram.
• Inspect the fuse for any signs of damage; replace it if necessary with a fuse of the same amperage.

3. Recharge Refrigerant

• Connect a refrigerant gauge to the low-pressure service port.
• Check the current refrigerant level; if it's low:
  • Use a refrigerant canister (R-134a or R-1234yf as applicable) and attach it to the low-pressure port.
  • Start the engine and turn on the AC to the maximum setting.
  • Slowly release the refrigerant until the system reaches the appropriate pressure level (refer to the manufacturer's specifications).

4. Inspect and Replace AC Compressor

• If the compressor is not engaging:
  • Remove the drive belt from the AC compressor.
  • Disconnect the electrical connector from the compressor.
  • Remove any mounting bolts and take out the compressor.
  • Install a new or remanufactured compressor, ensuring proper alignment and torque on the bolts.
  • Reconnect the electrical connector and reattach the drive belt.

5. Check AC Cabin Filter

• Locate the cabin air filter (usually behind the glove box).
• Remove the glove box to access the filter compartment.
• Take out the old filter and inspect it for dirt or blockages. Replace it with a new filter if necessary.
