Solution

1. Preparation

Gather tools and parts: Obtain an OBD-II scanner, manifold gauge set, basic hand tools, and a new cabin air filter if necessary.
Safety first: Disconnect the battery to avoid electrical shorts.

2. Check and Replace Fuses

Locate the fuse box (refer to the owner's manual).
Use a multimeter to test the AC fuse; replace it if it is blown.
Reconnect the battery and test the AC system.

3. Inspect and Test the AC Compressor

Reconnect the battery.
Start the engine and set the AC to the maximum setting.
Observe if the AC compressor engages; if not, proceed to troubleshoot further.
If the compressor is not engaging, check the electrical connections and relay.

4. Recharge the AC System

Connect the manifold gauge set to the high and low-pressure ports of the AC system.
Check the refrigerant pressure; if low, locate the refrigerant fill port.
Add the appropriate refrigerant (R-134a or R-1234yf) as specified in the owner's manual.
Monitor the pressure readings while adding refrigerant until they reach the manufacturer's specifications.

5. Replace Cabin Air Filter (if necessary)

Open the glove compartment and locate the cabin air filter cover.
Remove the cover and take out the old filter.
Insert the new cabin air filter, ensuring it is oriented correctly.
Reattach the cover and close the glove compartment.
