Sub-step 3: If low, proceed to add refrigerant according to the specifications (typically R-134a for this model).

3. Inspect the AC Compressor

Sub-step 1: Locate the AC compressor in the engine bay.
Sub-step 2: Inspect the compressor for any visible signs of damage or leaks.
Sub-step 3: Test the compressor operation by checking if it engages when the AC is turned on.

4. Replace Cabin Air Filter (if clogged)

Sub-step 1: Open the glove compartment and remove it to access the cabin air filter.
Sub-step 2: Remove the old cabin air filter and clean the filter housing.
Sub-step 3: Install the new cabin air filter, ensuring it is oriented correctly.

5. Check Electrical Components

Sub-step 1: Inspect the fuse panel for any blown fuses related to the AC system and replace them if necessary.
