Introduction
The windshield washer motor transmission is a critical component of the vehicle’s windshield washer system. It is responsible for driving the washer fluid pump, which delivers fluid to the windshield wipers. When the transmission fails, the washer fluid pump will not operate, and the windshield will not be cleaned properly. This article will guide you through troubleshooting the windshield washer motor transmission in a 1997 Lincoln Town Car.
Common Symptoms
The most common symptom of a faulty windshield washer motor transmission is the inability to activate the windshield washer pump. Other symptoms may include⁚
- A clicking sound when the washer switch is activated.
- The washer fluid pump runs intermittently.
- The washer fluid pump runs continuously.
Troubleshooting Steps
1. Check the Washer Fluid Level
Before you start troubleshooting the transmission, ensure that the washer fluid reservoir is full. A low fluid level can cause the pump to run dry, leading to damage to the transmission.
2. Inspect the Washer Motor Fuse
The washer motor fuse is typically located in the fuse box under the hood. Check the fuse for any signs of damage or blown elements. If the fuse is blown, replace it with a new fuse of the same amperage.
3. Test the Washer Motor Switch
The washer motor switch is located on the dashboard. To test the switch, use a multimeter to check for continuity between the switch terminals when the switch is activated. If there is no continuity, the switch is faulty and needs to be replaced.
4. Check the Washer Motor Wiring
Inspect the wiring leading to the washer motor for any signs of damage or corrosion. If the wiring is damaged, repair or replace it as needed.
5. Inspect the Washer Motor Transmission
If the washer motor and its wiring are in good condition, the problem may be with the transmission itself. To inspect the transmission, remove the washer motor from the vehicle and carefully examine it. Look for any signs of damage, such as cracks, broken parts, or excessive wear.
Replacing the Transmission
If the transmission is damaged, it will need to be replaced. To replace the transmission, follow these steps⁚
- Disconnect the battery.
- Remove the washer motor from the vehicle.
- Remove the old transmission from the washer motor;
- Install the new transmission onto the washer motor.
- Reinstall the washer motor in the vehicle.
- Reconnect the battery.
Conclusion
By following these troubleshooting steps, you can identify and repair a faulty windshield washer motor transmission in a 1997 Lincoln Town Car. Remember to always use caution when working on electrical components and to consult a qualified mechanic if you are unsure about any of the steps.
