why does my Skoda Octavia's AC blow warm air after a while

Solution

1. Preparation

• Gather tools (refrigerant gauge set, OBD-II scanner, socket set).
• Ensure the vehicle is parked on a level surface and the engine is cool.
• Disconnect the battery to ensure safety while working on electrical components.

2. Repair Leaks

• Sub-steps:
  1. If leaks are found, identify the source (e.g., hoses, condenser).
  2. Replace damaged hoses or components as necessary.
  3. Use AC sealant for minor leaks if applicable.
• Tools Required: Wrenches, AC sealant.
• Safety Warnings: Wear gloves and goggles when handling refrigerant.

3. Recharge the AC System

• Sub-steps:
  1. Attach the refrigerant gauge set to the low and high-pressure ports.
  2. Evacuate the system using a vacuum pump to remove moisture.
  3. Recharge the system with the correct type and amount of refrigerant (typically R-134a).
  4. Monitor the pressures to ensure they are within the manufacturer’s specifications.
• Tools Required: Vacuum pump, refrigerant canister, refrigerant gauge set.

4. Replace Cabin Air Filter

• Sub-steps:
  1. Locate the cabin air filter compartment (usually behind the glove box).
  2. Remove the old filter and clean the housing.
  3. Insert the new cabin air filter, ensuring it aligns properly.
• Tools Required: Screwdriver or socket set (if applicable).

5. Electrical System Check

• Sub-steps:
  1. Inspect and repair any damaged wiring or connectors in the AC system.
  2. Replace blown fuses related to the AC system operation.
  3. Test the AC control module for proper function.
• Tools Required: Multimeter, electrical connectors.
