3. Check and Recharge Refrigerant

Sub-steps:
1. Connect the manifold gauge set to the AC service ports (low and high side).
2. Check pressure readings against the manufacturer's specifications.
3. If low, add refrigerant to the system until proper levels are achieved.
4. Monitor the AC system for leaks after recharging.
Tools Required: Manifold gauge set, refrigerant canister
Safety Warnings: Wear gloves and goggles when handling refrigerants.

4. Inspect and Replace Blower Motor (if necessary)

Sub-steps:
1. Locate the blower motor, typically found under the dashboard on the passenger side.
2. Disconnect the electrical connector and remove the screws securing the blower motor.
3. Remove the blower motor and inspect for obstructions or damage.
4. Install a new blower motor if needed, securing it with screws and reconnecting the electrical plug.
