my Skoda Octavia NFL (2020-Present) AC not cooling in humid weather, what can I do?

Solution

1. Preparation

• Gather necessary tools and parts.
• Disconnect the vehicle battery to ensure safety during repair.

Tools Required:

• OBD-II scanner
• Refrigerant gauge
• Wrench set
• Screwdrivers
• Cabin air filter replacement (if needed)

2. Check Refrigerant Level

• Sub-step 1: Attach the refrigerant gauge to the low-pressure service port of the AC system.
• Sub-step 2: Check the pressure reading against manufacturer specifications; it should typically be between 30-40 PSI (at ambient temperature).
• Sub-step 3: If the pressure is low, proceed to recharge the AC system with the correct type of refrigerant.

3. Inspect and Replace Cabin Air Filter

• Sub-step 1: Locate the cabin air filter housing, usually behind the glove box.
• Sub-step 2: Remove the glove box if necessary to access the filter.
• Sub-step 3: Take out the old cabin air filter and inspect for dirt and debris.
• Sub-step 4: Install a new cabin air filter, ensuring it is properly seated.

4. Check AC Compressor Functionality

• Sub-step 1: Reconnect the battery and start the vehicle.
• Sub-step 2: Turn on the AC to the maximum setting.
• Sub-step 3: Listen for the AC compressor to engage (a clicking sound) and observe if the compressor clutch is spinning. If not, further diagnostic or replacement may be necessary.

5. Repair or Replace Faulty Components

• If any components such as the compressor, hoses, or expansion valve are found defective during inspection, replace them as necessary.
• Follow manufacturer specifications for torque values and connection sealing.
