Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface with the engine off.
Disconnect the negative battery terminal for safety.

2. Recharge Refrigerant

Tools Required: Manifold gauge set, refrigerant canister
Attach the manifold gauges to the low and high-pressure service ports.
Start the engine and turn on the AC to max.
Check the pressure readings; if low, proceed with recharging.
Slowly add refrigerant until proper pressure is reached according to specifications.

3. Inspect and Replace AC Compressor

Tools Required: Socket set, wrenches, torque wrench
Remove the serpentine belt by loosening the tensioner.
Unbolt the AC compressor from its mount and disconnect the electrical connector and refrigerant lines.
Install the new compressor by reversing the removal steps.
Ensure all connections are tight and torque to manufacturer specifications.

4. Check and Clean AC Condenser

Tools Required: Cleaning spray, soft brush
Inspect the condenser for debris or obstructions.
Clean the condenser with a gentle spray of water and a soft brush to remove dirt and debris.
Ensure proper airflow through the condenser.

5. Replace Cabin Air Filter

Tools Required: None
Locate the cabin air filter (usually behind the glove box).
Remove the old filter and replace it with a new one.
Ensure the filter is oriented correctly for airflow.
