Solution

1. Preparation

Tools Required: OBD-II scanner, multimeter, pressure gauge, basic socket set.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery to prevent electrical shorts.

2. Inspect and Replace Cabin Air Filter

Locate the cabin air filter housing, usually behind the glove compartment.
Remove the glove compartment by unscrewing any screws and releasing the retaining clips.
Open the filter housing and remove the old cabin air filter.
Inspect for debris or blockage; replace with a new cabin air filter if necessary.

3. Test and Replace Blower Motor

Reconnect the battery and turn on the ignition.
Use a multimeter to check the voltage at the blower motor connector while adjusting the fan speed.
If no voltage is present or if the motor does not operate, replace the blower motor.
Disconnect the battery again before replacing the blower motor.
Remove the blower motor assembly by unscrewing and disconnecting the wiring harness.
Install the new blower motor and reconnect the wiring.

4. Check and Recharge Air Conditioning System

Connect a pressure gauge to the high and low-pressure service ports of the A/C system.
Check refrigerant levels; if low, recover the refrigerant and recharge the system according to the manufacturer's specifications.
Use the appropriate refrigerant type (usually R-134a or R-1234yf) as specified in the vehicle manual.

5. Clear Error Codes

Use the OBD-II scanner to clear any error codes related to the climate control system.
Test drive the vehicle to ensure the climate control system operates correctly.
