Sounds like the micro switch inside the driver's door is bad. The computer doesn't realize that the driver's door is open. What about if you open the front passenger's door? Do the accessories work correctly then? If so it's definitely that micro switch. You may have to replace the entire latch assembly in the driver's door. Not sure if the switch is replaceable separately. HTH. - Jim

You're welcome. Glad to help. My money's still on those front door switches. They get the most use. Especially the driver's door. HTH. -Jim

but would that make the doors lock when in park and running. I have gotten out of truck and closed door while parked and idle and it locks me out.

It shouldn't with the driver's door and in park. Years ago I had a '78 Eldorado with automatic door locks. The doors would lock when you shifted out of park. In those days it was a feature only found on Cadillacs. I took the car through the car wash and the guy pulled the car up and let the driver's door close just enough to depress the switch for the automatic locks. When he got out and closed the door I was locked out. But in that case the car was in drive when the doors locked. Check the neutral safety switch as well. Almost sounds like the truck thinks it's not in park either. With the retained accessory power not shutting down when you open the door and it locking in park something's amiss with the doors and/or shifter. Do your reverse lights work? The neutral safety switch also doubles as the reverse light switch. If those lights are out too or come on in another gear it's out of adjustment. HTH. - Jim
