1. Blown fuse: Check the fuse box for a blown fuse labeled "windshield wipers" or "wipers." Replace the fuse if necessary.
2. Faulty wiper motor: The wiper motor is responsible for powering the wiper blades. If it's faulty, the blades won't move. To check the wiper motor, try manually moving the wiper blades. If they move freely, the motor is probably fine. If they're stuck, the motor may be faulty and need to be replaced.
3. Bad wiper switch: The wiper switch is responsible for turning the wipers on and off. If it's faulty, the wipers won't turn on. To check the wiper switch, try turning the wipers on and off. If they don't turn on, the switch may be faulty and need to be replaced.
4. Faulty wiring: The wiring that connects the wiper motor to the wiper switch may be faulty. This can prevent the wipers from working. To check the wiring, inspect it for any damage. If there's any damage, the wiring will need to be repaired or replaced.
5. Faulty relay: The relay is responsible for controlling the power supply to the wiper motor. If it's faulty, the wipers won't turn on. To check the relay, try swapping it out with another relay of the same type. If the wipers start working, the relay was faulty and needs to be replaced.
If you've checked all of these things and the wipers still don't work, you may need to take your Citroen to a mechanic for further diagnosis and repair.
