Solution

1. Preparation

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

2. Recharge Refrigerant

Tools Required: Refrigerant gauge, refrigerant canister.
Connect the refrigerant gauge to the low-pressure service port.
Check the pressure reading; if low, proceed to recharge.
Following the instructions on the refrigerant canister, add refrigerant until the correct pressure is reached.

3. Inspect and Replace AC Compressor

Tools Required: Socket set, torque wrench.
Remove the AC belt by loosening the tensioner.
Disconnect electrical connectors from the AC compressor.
Remove the mounting bolts and take out the compressor.
Install the new compressor by reversing the removal steps, ensuring all bolts are torqued to manufacturer specifications.

4. Replace Cabin Air Filter

Tools Required: None (but might require a flathead screwdriver).
Locate the cabin air filter access panel, usually behind the glove compartment.
Remove the panel and extract the old cabin air filter.
Insert the new cabin air filter, ensuring proper orientation, and replace the access panel.

5. Check and Replace Fuses/Relay

Tools Required: Fuse puller or pliers.
Locate the fuse box and identify the AC fuse and relay.
Remove the AC fuse and inspect it; replace it if blown.
Test the relay by swapping it with a similar one to check for functionality.
