1. Faulty Wiper Motor:
The wiper motor may have been damaged during the battery recharge process. Check the wiper motor and its electrical connections for any visible damage or loose wires. If the motor is damaged, it will need to be replaced.
2. Blown Fuse:
Although you mentioned that there are no blown fuses, recheck all the fuses related to the windshield wipers, including those in the fuse box under the hood and the fuse box inside the vehicle. A blown fuse can prevent the wipers from receiving power. Replace any blown fuses with the correct amperage.
3. Wiper Linkage Issues:
The wiper linkage is a system of rods and joints that connect the wiper motor to the wiper arms. If any of the linkage components are damaged or disconnected, it can prevent the wipers from moving. Inspect the wiper linkage for any issues and ensure it is properly connected to the wiper motor and the wiper arms.
4. Faulty Wiper Switch:
The wiper switch is responsible for controlling the movement of the wipers. If the switch is damaged or malfunctioning, it can prevent the wipers from working. Try turning the wiper switch on and off a few times to see if the wipers respond. If they don't, the wiper switch may need to be replaced.
5. Electrical Issues:
There may be an electrical problem preventing power from reaching the wiper motor. Check the wiring harness that connects the wiper motor to the battery or the fuse box. Ensure the connections are secure and there are no breaks in the wires. A multimeter can be used to test for continuity in the electrical circuit.
6. Software Issues (if applicable):
In modern vehicles equipped with advanced electronic systems, software glitches can sometimes affect the functionality of various components. If your vehicle has software updates available, try installing them to see if it resolves the issue with the windshield wipers.
If you are unable to identify or fix the problem yourself, it's best to take your vehicle to a qualified mechanic or auto electrician for further diagnosis and repair.
