Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative battery terminal to ensure safety.

2. Inspect and Replace Fuses

Locate the fuse box under the dashboard and the engine bay.
Remove the climate control fuse using a fuse puller.
Inspect the fuse; if burnt, replace it with a new fuse of the same amperage.
Reconnect the battery terminal.

3. Check Climate Control Module Connections

Remove the trim panel surrounding the climate control unit.
Unscrew and gently pull out the climate control module.
Verify that all connectors are securely attached; reconnect if necessary.
Reassemble the module and trim panel.

4. Test and Replace Blower Motor (if necessary)

Locate the blower motor, usually found under the dashboard on the passenger side.
Disconnect the electrical connector and remove any retaining screws.
Test the blower motor by applying a direct voltage from a battery; if it does not operate, replace it.
Install the new blower motor in reverse order of removal.

5. Recharge Refrigerant (if necessary)

Connect a refrigerant gauge to the low-pressure port of the AC system.
Check the refrigerant levels; if low, add the appropriate refrigerant type (R-1234yf).
Monitor the system while adding refrigerant to achieve desired pressure levels.
