Therefore, finding and replacing involves these steps:
1. Identifying the faulty component:
* Is it the switch itself? If the buttons don't light up or register presses at all, the problem is likely the switch assembly. This is relatively easy to replace, but requires removing the bezel surrounding the climate controls.
* Is it a blend door actuator? If the temperature isn't changing as expected (e.g., you select hot, but get cold air), the blend door actuator is suspect.
* Is it a mode door actuator? If you can't select defrost, floor, or vent properly, the mode door actuator is likely at fault.
2. Locating the actuator(s):
The actuators are usually located inside the dashboard behind the climate control panel. Accessing them requires significant disassembly. This is NOT a simple job and requires patience and mechanical aptitude. You'll likely need:
* Repair manual: A Haynes or Chilton manual for your specific year Windstar will provide detailed instructions and diagrams. This is crucial to avoid damaging anything during disassembly.
* Tools: Screwdrivers (Phillips and flathead), possibly trim removal tools to avoid scratching the plastic, and possibly torx bits.
3. Replacement Process (General Steps – Consult your repair manual for specific details):
* Disconnect the battery: This is essential to prevent short circuits.
* Remove the climate control panel: This typically involves removing the surrounding trim pieces and unscrewing the control panel itself.
* Locate the suspect actuator: The repair manual will show you where to find the blend door and mode door actuators.
* Disconnect the electrical connector: Carefully unplug the electrical connector from the actuator.
* Remove the actuator: This usually involves removing screws or clips holding it in place.
* Install the new actuator: Install the new actuator, ensuring it's properly seated and secured.
* Reconnect the electrical connector: Make sure it's securely plugged in.
* Reassemble everything: Carefully reassemble the climate control panel and trim pieces in reverse order of disassembly.
* Reconnect the battery: Test the climate controls to ensure they are functioning correctly.
Where to buy parts:
* Auto parts stores: Advance Auto Parts, AutoZone, NAPA, etc., will likely have the actuators or the climate control switch itself. Provide them with your vehicle's year, make, and model.
* Online retailers: Amazon, eBay, and other online retailers offer both new and used parts. Be sure to check reviews before purchasing.
* Ford dealerships: Dealerships will have genuine Ford parts, but they will likely be the most expensive option.
Important Note: If you are not comfortable working on your vehicle's dashboard, it's best to take it to a qualified mechanic. Improper disassembly can lead to damage to other components and potentially costly repairs. The dashboard is complex, and improper reassembly can lead to rattles and other issues. Always consult a repair manual specific to your year and model.
