Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the engine is off.
Disconnect the battery to avoid electrical issues.

2. Check Refrigerant Level

Tools Required: Manifold gauge set
Connect the low-pressure side of the manifold gauge to the AC service port.
Check the gauge reading; if it is below the manufacturer's specifications, proceed to recharge the system.

3. Recharge the AC System

Parts Required: Refrigerant (R-134a or as specified)
Attach the refrigerant can to the manifold gauge set.
Open the low-pressure valve and start the engine with AC on high.
Monitor the gauge and fill until it reaches the correct level.
Close the valve and disconnect the refrigerant canister.

4. Test the AC Compressor

Tools Required: Multimeter
Reconnect the battery.
Start the engine and turn on the AC to maximum.
Use a multimeter to check for voltage at the AC compressor connector.
If there is voltage but the compressor does not engage, replace the compressor.

5. Inspect and Replace Components

Check the AC relay and fuse for continuity.
If either is faulty, replace them with new components.
Inspect the cabin air filter; replace if clogged.
