One problem related to trunk wiring has been reported for the 1999 Ford Windstar. The most recently reported issues are listed below.
The Windstar was parked in our driveway outside. Engine cold and turned off. Our son saw smoke outside coming from the engine compartment. We raised the hood carefully and put fire out with fire ext. And garden hose. Fire was under the brake master cylinder on the drivers side engine compartment. Wiring harness burned and other components by speed control deactivation switch catching fire. We had this switch replaced in a Ford recall, but appears the repair was done incorrectly (fuse installed on wrong side of wiring harness, allowing the switch to remain hot). So fortunate that the car was not parked in the garage, for I would not be writing this review today!.
