1. Check the fuses: There may be a blown fuse that is preventing the blower from receiving power. Check the fuse box for the AC blower fuse and replace it if necessary.
2. Check the relay: The relay is a small electrical component that controls the power flow to the blower. If the relay is faulty, the blower will not receive power and will not work. Check the relay and replace it if necessary.
3. Check the blower motor: The blower motor is the component that actually moves the air through the vents. If the blower motor is faulty, it will not be able to move air and the AC will not work. Check the blower motor and replace it if necessary.
4. Check the climate control panel: The climate control panel is the interface that you use to control the AC settings. If the climate control panel is faulty, it may not be able to send the correct signals to the blower motor, causing it not to work. Check the climate control panel and replace it if necessary.
5. Check the wiring: There may be a problem with the wiring that is preventing the blower from receiving power. Check the wiring for any damage or loose connections and repair or reconnect as necessary.
6. Check the AC system refrigerant: If AC system refrigerant is low or empty then it can effect the performance of AC system.
If you are not comfortable performing these checks and repairs yourself, you should take your car to a qualified mechanic for further diagnosis and repair.
