Solution

1. Preparation

Tools Required: OBD-II scanner, refrigerant gauge set, multimeter, socket set, screwdrivers, safety glasses, gloves
Ensure the vehicle is parked on a flat surface and the engine is turned off.

2. Check and Recharge Refrigerant

Locate the low-pressure service port on the AC system.
Connect the refrigerant gauge set to the port.
Read the pressure; if it is low, proceed to recharge.
Purchase the correct R-134a refrigerant.
Following the manufacturer’s instructions, attach the refrigerant can and recharge the system.

3. Inspect AC Compressor

Disconnect the battery to ensure safety.
Remove any obstructions to access the AC compressor.
Check the compressor for visible damage or leaks.
If the compressor is not engaging, test the electrical connections and relay with a multimeter.

4. Replace Cabin Air Filter

Locate the cabin air filter compartment, typically behind the glove box.
Remove the glove box to access the filter.
Pull out the old cabin air filter and check for dirt and debris.
Install a new cabin air filter according to the manufacturer's specifications.

5. Test the AC System

Reconnect the battery and start the engine.
Set the AC to the maximum setting and monitor the air temperature from the vents.
If the system is still not blowing cold air, further investigation into the expansion valve or evaporator may be necessary.
