Solution

1. Preparation

Gather all necessary tools and parts.
Disconnect the vehicle battery to ensure safety during repairs.

2. Check and Replace AC Fuse

Locate the fuse box (usually under the dashboard or in the engine compartment).
Remove the AC fuse and inspect for any signs of damage or breakage.
Replace the fuse with one of the same amperage rating if it's blown.
Reconnect the battery and test the AC system.

3. Inspect and Replace AC Relay

Find the AC relay in the fuse box.
Remove the relay and test it using a multimeter to check for continuity.
Replace the relay with a new one if it is faulty.
Reinstall the relay and reconnect the battery to test the AC.

4. Test Blower Motor

If the AC still does not work, locate the blower motor.
Disconnect the blower motor connector.
Use jumper wires to apply direct power to the motor.
If the motor operates, replace it. If not, further diagnostics are required.

5. Check Wiring and Connections

Visually inspect all wiring and connectors related to the AC system.
Look for any frayed wires, corrosion, or loose connections.
Repair or replace any damaged wiring or connectors as necessary.
