Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery to avoid electrical issues during repair.

2. Replace Cabin Air Filter

Tools Required: Screwdriver, new cabin air filter.
Locate the cabin air filter housing, typically behind the glove box.
Open the glove box and remove any screws or clips holding the housing cover.
Take out the old cabin air filter and clean any debris from the housing.
Install the new cabin air filter, ensuring it is oriented correctly.
Reattach the housing cover and secure the glove box.

3. Recharge AC System

Tools Required: AC refrigerant kit, pressure gauge.
Connect the pressure gauge to the low-side service port of the AC system.
Check the refrigerant pressure; if low, proceed to recharge.
Follow the refrigerant can instructions, connecting the hose and slowly adding refrigerant until the proper pressure is reached.
Disconnect the hose after refilling and check for leaks.

4. Inspect and Clean AC Condenser

Tools Required: Hose, soft brush, cleaner.
Locate the AC condenser in front of the engine radiator.
Carefully remove any debris or dirt using a soft brush and rinse with water.
Check for any signs of damage or bent fins; replace if necessary.

5. Test Blower Motor

Tools Required: Multimeter.
Access the blower motor, usually located under the dashboard on the passenger side.
Disconnect the blower motor connector and test for voltage using a multimeter.
If there's no voltage, check the blower motor resistor and replace if faulty.
If the blower motor is functioning improperly, replace it.
