Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the battery to ensure safety during electrical work.

2. Inspect and Replace Fuses

Locate the fuse box (typically under the dashboard or in the engine compartment).
Remove the cover and locate the climate control fuse using the diagram.
Inspect the fuse for continuity; replace with a new fuse of the same rating if blown.

3. Verify and Replace Cabin Air Filter

Locate the cabin air filter access panel (usually behind the glove box).
Remove the glove box for better access if necessary.
Remove the old cabin air filter and inspect for dirt and debris.
Install a new cabin air filter, ensuring it is oriented correctly.

4. Check and Replace Blower Motor

Remove the blower motor assembly from its housing (usually located under the dashboard).
Test the blower motor with direct power to confirm operation; replace if it does not function.
Install the new blower motor, securing it with the appropriate screws and connectors.

5. Refrigerant Level Check

Connect a refrigerant gauge to the A/C service ports.
Check the pressure levels; if low, locate the leak, repair it, and recharge the system with the appropriate refrigerant type.
Ensure all connections are tight and secure after recharging.
