I have a 2008 F150. I went to leave for work this morning and it will not come out of park. after checking the owners manual, i checked all tail and brake lights and the fuses and all are good . I read on here about the Brake Interlock and went about checking the wires going in and out. With the motor running there is juice in one wire only and with the brake pedal depressed there is juice in both wires. So that is good . Any ideas where to go from here?
