Solution

1. Preparation

Tools Required: Socket set, coolant catch pan, OBD-II scanner, multimeter, flathead screwdriver.
Allow the engine to cool before starting any work to avoid burns.

2. Coolant Level Check

Locate the coolant reservoir.
Remove the cap and visually inspect the coolant level. If low, top off with the appropriate coolant mixture (50/50 coolant and distilled water).
Run the engine to circulate the coolant and check for leaks.

3. Inspect Heater Core

Remove the dashboard panel covering the heater core (may require a flathead screwdriver).
Inspect for any visible leaks or corrosion on the heater core.
If blocked, flush the heater core using a garden hose.

4. Thermostat Inspection

Locate the thermostat housing, typically near the engine block.
Remove the thermostat (if necessary) and check its operation by placing it in boiling water to see if it opens.
If faulty, replace with a new thermostat, ensuring proper torque on bolts (usually around 15-25 Nm).

5. HVAC Control Module Check

Use the OBD-II scanner to check for any fault codes related to HVAC.
Test the blower motor using a multimeter to ensure it receives power.
If the blower motor is faulty, replace it.

6. Cabin Air Filter Replacement

Locate the cabin air filter access panel, usually behind the glove compartment.
Remove the old filter and check for debris or blockage.
Install a new filter, ensuring it is oriented correctly.
