why does my Honda Civic 10th Generation (2016-2021) air conditioning stop working

Solution

1. Preparation

• Gather all necessary tools and parts.
• Ensure the vehicle is parked on a level surface and the engine is off.
• Disconnect the negative battery terminal to prevent electrical shock.

2. Check Refrigerant Levels

• Connect the manifold gauge set to the low and high-pressure service ports.
• Start the engine and turn the AC to maximum cooling.
• Read the pressure levels on the gauges; if low, proceed to recharge or repair leaks.

3. Inspect and Replace the Cabin Air Filter

• Locate the cabin air filter compartment, typically behind the glove box.
• Remove the glove box and access the filter housing.
• Take out the old filter and check for debris; replace with a new filter if necessary.
• Reassemble the glove box.

4. Replace the AC Compressor (if necessary)

• Disconnect the refrigerant lines from the AC compressor using the appropriate tools.
• Remove the mounting bolts securing the compressor using a socket set.
• Install the new compressor in reverse order, ensuring to torque bolts to manufacturer specifications.
• Reconnect the refrigerant lines and ensure they are sealed properly.

5. Recharge the AC System

• Use a refrigerant recovery machine to recover any remaining refrigerant.
• Follow the manufacturer's specifications to recharge the system with the correct type and amount of refrigerant.
• Run the AC system for a few minutes to check for leaks and ensure proper operation.
