Solution

1. Preparation

Gather tools and parts.
Disconnect the negative battery terminal to ensure safety.
Allow the vehicle to cool down before working on the AC system.

2. Check and Refill Refrigerant

Tools Required: Manifold gauge set, refrigerant (R-134a), safety goggles, gloves.
Connect the manifold gauge set to the AC service ports.
Read the pressure levels; if low, proceed to refill.
Follow the manufacturer's instructions to add refrigerant until the system reaches the specified pressure.
Disconnect the gauge set carefully and securely close the service ports.

3. Inspect and Replace Components

Tools Required: Socket set, screwdrivers, torque wrench.
Inspect the AC compressor and its electrical connections:
- If damaged, remove the AC compressor by unscrewing the mounting bolts and disconnecting the electrical connector and refrigerant lines.
- Replace with a new AC compressor and ensure all connections are tight.
Check the AC fuses and relays located in the fuse box:
- Replace any blown fuses or faulty relays with new ones of the same rating.

4. Clean or Replace Cabin Air Filter

Tools Required: None.
Locate the cabin air filter housing, usually found behind the glove compartment.
Remove the old filter and check for clogs.
Clean the housing area and install a new cabin air filter.

5. Test AC System

Reconnect the negative battery terminal.
Start the engine and turn the AC to the maximum setting.
Ensure the AC compressor engages and check for cold air from the vents.
