Solution

1. Preparation

• Gather tools: manifold gauge set, basic hand tools, OBD-II scanner, safety goggles, and gloves.
• Ensure the vehicle is parked on a level surface and the engine is turned off.

2. Check Refrigerant Levels

• Sub-steps:
  1. Connect the manifold gauge set to the low and high-pressure ports of the AC system.
  2. Start the engine and turn on the AC to maximum setting.
  3. Read the pressure levels on the gauges; refer to manufacturer specifications for correct ranges.
• Tools Required: Manifold gauge set

3. Inspect the AC Compressor

• Sub-steps:
  1. Visually inspect the AC compressor for damage or leaks.
  2. Check if the AC compressor clutch is engaging when AC is turned on.
  3. If not engaging, test the clutch with a multimeter for electrical continuity.
• Tools Required: Multimeter

4. Check AC Fuses and Relays

• Sub-steps:
  1. Locate the fuse box under the dashboard and engine compartment.
  2. Inspect the AC-related fuses and relays for any signs of damage or blown fuses.
  3. Replace any faulty fuses or relays.
• Tools Required: Fuse puller or flathead screwdriver
