Instead of fixing it, you should *troubleshoot* it to find the cause of the malfunction and then have it repaired by a qualified mechanic. Here's a breakdown of how to approach the problem:
1. Identify the Problem:
* Is the Traction Control light on? This is the most common indicator of a problem. The light might flash or stay illuminated.
* What's the symptom? Is the traction control not engaging when you expect it to? Is the light on constantly? Is there a different related issue, such as ABS malfunction (they are often linked)?
2. Check the Obvious:
* Tires: Low tire pressure, worn tires, or tires with different tread depths can affect traction control. Check your tire pressure and condition.
* Wheels: Ensure all wheels are properly mounted and that no components are damaged or loose.
3. Diagnostic Trouble Codes (DTCs):
* A professional mechanic will use an OBD-II scanner to read any diagnostic trouble codes (DTCs) stored in the vehicle's computer. These codes pinpoint specific faults within the TCS or related systems. This is the most crucial step in determining the cause.
4. Possible Causes (requiring professional diagnosis and repair):
* Faulty Wheel Speed Sensor(s): These sensors monitor wheel rotation and are essential for the TCS to function.
* Bad ABS Module: The ABS (Anti-lock Braking System) module is often integrated with the TCS, and a fault here can affect both systems.
* Steering Angle Sensor: This sensor is sometimes used to inform the TCS about the direction the vehicle is traveling.
* Faulty Traction Control Module: The TCS module itself might be defective.
* Wiring Issues: Damaged or corroded wiring can interrupt signals to and from the TCS components.
5. Repair:
Once the mechanic has identified the faulty component using the diagnostic codes, they can replace or repair the necessary part. This will typically involve:
* Replacing a sensor: This is often a relatively straightforward repair.
* Repairing or replacing wiring: This can be more complex, depending on the extent of the damage.
* Replacing the ABS module or TCS module: These are more involved repairs and usually expensive.
In short: Don't try to fix the traction control system yourself unless you have extensive automotive electrical and diagnostic experience. Take your Ford Windstar to a qualified mechanic for proper diagnosis and repair. Attempting repairs without the right knowledge and tools could worsen the problem or even damage other components.
