LEE COUNTY, Fla.- Hundreds of Lee County school buses will be out of commission for a couple weeks.

Some of the buses caught fire last May at the facility in Buckingham. Those fires were initially said to be electrical in nature. Today, the district transportation director said that during that investigation, the Navistar Corporation found faulty wiring in the air conditioning units. Though we don't know yet if the wiring in those units is what sparked the fire.

Now, a crew will come next week to make repairs to 250 buses. Until then, all of them will stay parked.
