why does my Genesis G70 AC blow warm air after a while

Solution

1. Preparation

• Gather tools and parts required for the repair.
• Ensure the vehicle is parked on a flat surface and the engine is off.
• Disconnect the battery to ensure safety while working on electrical components.

2. Check Refrigerant Levels

• Tools Required: Manifold gauge set
• Connect the manifold gauges to the high and low-pressure ports of the AC system.
• Read the pressure levels; if low, proceed to recharge the refrigerant.
• If high, consider potential blockages or a malfunctioning compressor.

3. Recharge Refrigerant

• Tools Required: Refrigerant canister with proper type (R-134a or R-1234yf as specified)
• Attach the refrigerant canister to the low-pressure port.
• Add refrigerant slowly while monitoring the gauges. Ensure the low side pressure is within manufacturer specifications.
• Close the canister valve and disconnect the gauges.

4. Inspect and Replace Components

• Tools Required: Socket set, screwdrivers
• If the compressor or condenser is faulty, replace them:
  • Compressor Replacement:
    • Remove the compressor drive belt.
    • Disconnect the electrical connections and refrigerant lines (ensure proper recovery of refrigerant).
    • Remove mounting bolts and take out the old compressor.
    • Install the new compressor, ensuring all connections are tight and leak-free.
  • Condenser Replacement:
    • Remove any panels obstructing access to the condenser.
    • Disconnect the refrigerant lines and electrical connectors.
    • Remove mounting bolts and take out the old condenser.
    • Install the new condenser and reattach connections.

5. Reassemble and Test

• Reconnect battery terminals.
• Start the vehicle and test the AC system for proper cooling function.
• Monitor for any unusual noises or performance issues.
