Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery to prevent electrical shocks.

2. Check and Recharge Refrigerant

Tools Required: Refrigerant gauge, recovery machine, refrigerant canister.
Connect the refrigerant gauge to the service ports on the AC system.
Measure the low and high-pressure readings; refer to manufacturer specifications.
If levels are low, use a recovery machine to remove old refrigerant and recharge with the correct type and amount of refrigerant.

3. Replace Cabin Air Filter

Tools Required: Screwdriver or trim removal tool.
Locate and remove the glove box or access panel to reach the cabin air filter.
Remove the old cabin air filter and inspect for dirt and debris.
Install a new cabin air filter, ensuring it is oriented correctly.

4. Inspect and Replace AC Compressor (if necessary)

Tools Required: Socket set, torque wrench, AC compressor replacement kit.
Disconnect the refrigerant lines from the AC compressor and cap them immediately to prevent contamination.
Unbolt the AC compressor from its mounting bracket.
Replace with a new AC compressor, ensuring all bolts are torqued to manufacturer specifications.
Reconnect the refrigerant lines and recharge the AC system.

5. Verify Blower Motor Operation

Tools Required: Multimeter.
Locate the blower motor and test for continuity using a multimeter.
If the blower motor is faulty, replace it according to manufacturer specifications.
