Solution

1. Preparation

Gather all necessary tools and parts.
Disconnect the negative battery terminal to ensure safety.

2. Check and Replace AC Fuse

Locate the fuse box (usually under the dashboard or in the engine compartment).
Identify the AC compressor fuse using the diagram on the fuse box cover.
Remove the fuse using a fuse puller or needle-nose pliers.
Inspect the fuse for continuity; replace if blown with an equivalent fuse.

3. Inspect and Recharge Refrigerant

Connect the manifold gauge set to the low and high-pressure service ports of the AC system.
Check the pressure readings; if low, proceed to recharge.
Use a refrigerant canister and follow the instructions to add refrigerant, ensuring not to overfill.
Disconnect the gauges and replace the service port caps.

4. Test AC Compressor Operation

Reconnect the negative battery terminal.
Start the vehicle and turn the AC to maximum cold.
Observe the AC compressor; it should engage. If not, check the wiring and connectors for damage.

5. Repair or Replace Faulty Components

If the compressor fails to engage, test the AC relay; replace it if defective.
If there are leaks in the system, identify the source, and repair or replace the affected components (hoses, evaporator, etc.).
