The radio and power windows stay on and light does not come

Customer Question

The radio and power windows stay on and light does not come on when key is removed and door opened
JA: Have you checked the fuses? Have you checked the door switches?
Customer: checked fuses/checked relays/ opened both front doors
JA: What is the model/year of your Ford?
Customer: 2006 F350
JA: Are you fixing your F350 yourself? What have you tried so far?
Customer: Yes I am fixing it myself. Put a new ignition in about a year ago because the radio and windows and gauges would go off and then come back on. sometimes it would go for months and sometimes it would be 5 times a day or 5 times in 5 minutes. Replaced gauge display package and now when you shut off engine, remove the key and open the door. Windows and radio stay on and light does not come on. Have checked both front doors.
JA: Anything else you want the mechanic to know before I connect you?
Customer: that is about it

The problem is actually a bad door ajar switch in the drivers door. The switch is mounted on the door latch inside the drivers door. The switch opens when the drivers door is opened which will turn the accessory power off after the key is removed from the ignition and the drivers door is opened. Replace the drivers door ajar switch to fix this problem.
