Solution

1. Preparation

Gather tools: refrigerant gauge, OBD-II scanner, multimeter, basic hand tools (screwdrivers, wrenches).
Ensure the vehicle is parked on a level surface with the engine off.
Disconnect the negative battery terminal for safety.

2. Check and Recharge Refrigerant

Sub-steps:
1. Connect the refrigerant gauge to the low-pressure service port.
2. Read the pressure levels; refer to the manufacturer's specifications.
3. If low, add refrigerant according to specifications (R-134a for this model).
4. Monitor the system for proper cooling after recharging.

3. Inspect and Replace the AC Compressor

Sub-steps:
1. Locate the AC compressor and check for any visible signs of damage or leaks.
2. If the compressor does not engage, test the electrical connections with a multimeter for continuity.
3. If faulty, remove the AC compressor by disconnecting the refrigerant lines (ensure proper recovery of refrigerant).
4. Install the new compressor, ensuring all seals and O-rings are replaced.
5. Reconnect the refrigerant lines and recharge the AC system.

4. Check and Replace Cabin Air Filter

Sub-steps:
1. Locate the cabin air filter housing (usually behind the glove box).
2. Remove the glove box if necessary to access the filter.
3. Take out the old filter and inspect for dirt or blockages.
4. Install a new cabin air filter according to the manufacturer’s specifications.
