why does my Skoda Octavia's air conditioning blow hot 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 to prevent electrical accidents.

2. Recharge Refrigerant

• Tools Required: Manifold gauge set, refrigerant canister
• Connect the manifold gauges to the low and high-pressure service ports.
• Start the engine and turn the AC to maximum.
• Check pressure readings: if low, proceed to add refrigerant.
• Open the refrigerant canister valve slowly while monitoring the low-pressure gauge.
• Shut off the valve when pressures are within the manufacturer's specifications.
• Disconnect the gauges and reconnect the service port caps.

3. Replace Cabin Air Filter (if necessary)

• Tools Required: Screwdriver or trim removal tool
• Locate the cabin air filter access panel, typically under the dashboard or behind the glove compartment.
• Remove screws or clips and take off the panel.
• Slide out the old cabin air filter and insert a new one, ensuring it's oriented correctly.
• Reinstall the access panel and secure it with screws or clips.

4. Inspect and Replace AC Compressor (if failed)

• Tools Required: Socket set, wrenches, AC compressor removal tool
• Remove the drive belt from the AC compressor by loosening the tensioner pulley.
• Disconnect electrical connectors and refrigerant lines from the compressor.
• Unbolt the AC compressor from its mounting brackets.
• Install the new compressor by reversing the removal steps, ensuring all connections are secure.
• Recharge the AC system with refrigerant.
