To fix air conditioning problems in the 2020 Chevrolet Bolt EV, you can follow these detailed steps. Ensure you exercise caution and consult a professional mechanic where necessary:

Check the Basic Settings

• Ensure that the A/C system is turned on and the desired temperature is set correctly.
• Verify that the fan speed is adequate and the air vents are open and unblocked.
• Check if the recirculation button is activated, as this may restrict air flow into the cabin.

Investigate the Electrical System

• Inspect the A/C fuse in the fuse box to ensure it has not blown. Replace it if necessary.
• Check the A/C system's electrical connections for any loose connections or damaged wires.
• Make sure the climate control settings are displaying properly on the dashboard. A malfunctioning display could indicate an internal issue.

Examine the Coolant Levels and System Integrity

• Check the refrigerant level of the air conditioning system using a pressure gauge. If the level is low, it might need a recharge. It is advised to let a professional handle refrigerant recharging as it requires special equipment.
• Look for signs of leaks in the refrigerant lines or components, such as noticeable hissing sounds or oily residue.
• Inspect the coolant system for any blockages or damage that could affect A/C performance.

Evaluate the Air Conditioning Components

• Inspect the air conditioning compressor to ensure it is engaging properly. A faulty compressor might require replacement or repair.
• Check the A/C condenser for any obstruction or debris that might be affecting its function.
• Examine the cabin air filter for dirt or blockage and replace it if necessary.

Test the Climate Control System

• Run a diagnostic test on the climate control system if your Bolt has the capability. This may require a specialized OBD-II scanner.
• Look for any error codes that could indicate specific issues within the climate control system.

Seek Professional Assistance

• If you are unable to diagnose or fix the issue yourself, contact a certified Chevrolet technician or visit a professional mechanic specializing in EVs.
• Ensure that any service provider you engage uses appropriate equipment for electric vehicles due to their specialized systems and components.

By following these steps diligently, you can identify and potentially resolve the air conditioning issues in your 2020 Chevrolet Bolt EV.
