Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the vehicle battery to ensure safety while working on electrical components.

2. Inspect and Replace Fuses

Locate the fuse box, typically found in the glove compartment or under the dashboard.
Use the fuse diagram to identify the climate control fuse.
Remove the fuse using a fuse puller and check if it's blown.
Replace with a new fuse of the same amperage if necessary.

3. Test and Replace Blower Motor

Reconnect the battery and turn on the climate control system.
Use a multimeter to check for voltage at the blower motor connector while the system is on.
If no voltage is present, trace back to the climate control module for potential failure.
If voltage is present but the blower does not operate, replace the blower motor.

4. Check Climate Control Module

If error codes related to the climate control module were found, it may require reprogramming or replacement.
Remove the climate control module from the dashboard by carefully detaching it from its housing.
Inspect for any visible damage or burnt components.
If necessary, replace with a new or refurbished module and reprogram as needed.

5. Replace Cabin Air Filter

Locate the cabin air filter housing, often situated behind the glove box.
Remove the glove box for access.
Take out the old cabin air filter and replace it with a new one, ensuring correct orientation.
