my Genesis G70 AC is blowing hot air what could be wrong

Solution

1. Preparation

• Gather tools and parts required for the repair.
• Ensure the vehicle is parked on a level surface and the engine is off.
• Disconnect the battery to prevent electrical shocks.

2. Recharge Refrigerant

• Tools Required: Refrigerant gauge set, vacuum pump, refrigerant canister.
• Connect the refrigerant gauge set to the low-pressure service port of the AC system.
• Check the pressure readings; if low, proceed to recharge.
• Use a vacuum pump to remove air from the system for about 30 minutes, then close the valve.
• Add refrigerant according to the manufacturer’s specifications (usually R-134a), monitoring the gauge.

3. Inspect and Replace AC Components

• Tools Required: Socket set, wrenches, screwdrivers, AC manifold gauge set.
• If the compressor is not engaging, check the electrical connections and replace any faulty relays or fuses.
• If the compressor is damaged, disconnect it from the AC lines and electrical connections, then remove it.
• Install the new compressor and reconnect all lines securely, ensuring no leaks.
• Replace the cabin air filter if clogged to improve airflow.

4. Test the System

• Reconnect the battery and start the engine.
• Turn on the AC to the maximum setting and monitor for proper cooling.
• Check for any unusual noises or leaks around the AC components.
