Solution

1. Preparation

Gather all necessary tools and parts.
Disconnect the vehicle battery to ensure safety while working on electrical components.
Allow the vehicle to cool down if the engine has been running.

2. Inspect and Replace Fuses

Locate the fuse box (typically found under the dashboard or in the engine compartment).
Using a fuse puller, check the climate control fuses for any damage.
Replace any blown fuses with new ones of the same amperage.

3. Replace Cabin Air Filter

Open the glove compartment and remove any contents.
Detach the glove compartment from its hinges for better access.
Locate the cabin air filter housing and remove the cover.
Extract the old cabin air filter and insert a new one, ensuring it is oriented correctly.

4. Test and Replace Blower Motor

Using a multimeter, test the voltage at the blower motor connector while the climate control is set to different speeds.
If no voltage is detected, further diagnose the wiring or climate control module.
If the blower motor is faulty, disconnect it, remove any screws or clips holding it in place, and replace it with a new motor.

5. Recharge Refrigerant (if applicable)

Connect a refrigerant gauge to the AC service ports.
If refrigerant levels are low, use an AC recharge kit to add the appropriate amount of refrigerant as specified in the owner’s manual.
Monitor the AC performance after recharging.
