why does my Skoda Octavia's air conditioning blow warm air?

Solution

1. Preparation

• Gather tools and materials: refrigerant, manifold gauge set, socket set, screwdrivers, and safety glasses.
• Ensure the vehicle is parked on a level surface and the engine is off.
• Disconnect the battery to ensure safety while working on electrical components.

2. Recharge the AC System

• Tools Required: Manifold gauge set, refrigerant.
• Connect the low-pressure side of the manifold gauge set to the AC service port.
• Open the valve to check the refrigerant level; if low, proceed to recharge.
• Follow the manufacturer’s specifications for the correct amount of refrigerant.
• After recharging, run the AC system to check if cold air is restored.

3. Inspect and Replace the Cabin Air Filter

• Tools Required: Screwdrivers, replacement cabin air filter.
• Locate the cabin air filter housing, typically behind the glove box.
• Remove the glove box or cover to access the filter.
• Take out the old filter and inspect for dirt and blockages.
• Install the new cabin air filter in the correct orientation.

4. Replace the AC Compressor (if faulty)

• Tools Required: Socket set, torque wrench, refrigerant recovery machine (if needed).
• Discharge the refrigerant from the system using a recovery machine.
• Disconnect electrical connectors and hoses from the AC compressor.
• Remove the mounting bolts securing the compressor to the engine.
• Install the new compressor, ensuring all connections are tight and secure.
• Recharge the AC system with refrigerant.
