A fire that engulfed a parked truck on July 27 was sparked by a malfunction in the cruise control electrical circuit, according to Fire Marshal Cody Derrick.
Derrick determined the cause after reviewing surveillance cameras captured the incident, interviews with the owner and an insurance claims adjuster and researching the faulty cruise control circuit.
A manufacturer's recall was issued for the 1997-2003 Ford F-150 and other models for the cruise control switch in 2009. The switch was hardwired to the brake light circuit, which maintains a constant power supply as required by law. The switches corrode over time and combust.
Derrick said surveillance footage showed no one was near the vehicle when a jet of flames leaped more than 30 feet into the air from under the hood. The fire quickly destroyed the engine and cab of the truck before firefighters extinguished the flames.
The flames also damaged other cars parked nearby.
