A fire was caused by the failure of the power steering cooling fan. At some point the day of the incident the fan seized and the resulting electrical resistance in the main wiring harness caused the wiring harness to heat to a point of melting some of the plastic wire insulation allowing for direct wire to wire contact and resulted in an electrical fire between the engine and the passenger compartment. The resulting fire completely disabled the vehicle's electrical system and requires at Minimum the replacement of the entire main wiring harness. Event description after a short drive (less than 2 miles on a cold engine) the vehicle was parked. After the engine was turned off smoke was seen rising from the vehicle engine compartment. Upon raising the hood, flames were seen between the engine and the passenger compartment reflecting off both fire walls. 2 fire extinguishers were required to put out the flames after the battery was disconnected. Total loss of the vehicle to fire was prevented by the owners actions.
