Ford is recalling more than a million of its F-150 pickup trucks.  They're being recalled to fix air bags that could deploy without warning and possibly injure drivers. In February, Ford agreed to recall nearly 150,000 F-150 trucks, but Thursday announced it's now recalling around a million more. The recall only affects trucks from the 2004 through 2006 model years and local dealers say the recall is for only specific models from those years. The recall is for a small wiring part inside the steering column that isn't properly insulated and could short out, causing the airbag to deploy inadvertently. With this recall, Ford service centers will replace that part with a new, properly insulated wire for free. Ron Carstensen, General Manager of Meridian Ford tells Idaho's news channel 7 that  affected F-150 owners will get a letter in the mail.  He says if you get a letter, call your local Ford dealership and be ready to give them your VIN number.  Carstensen estimates the repair should take between an hour and a half and two hours.  He says the replacement parts are currently in short supply, but says Ford is increasing manufacturing to get the recall handled as fast as possible.
