Hello, I have a 2009 F150 lariat. When I turn the truck off and pull the key out and open the door, the radio does not shut off or the doors do not unlock like they used to. Tried the wd-40 and it worked for about a week so went ahead replaced the door latch. Still does not work. Is there something else I'm missing? I have searched for months to find a wire messed up and they are all good.

 

When would the doors normally unlock?
When you put it in park or when you turn the ignition off or open the door.
I'm wondering if it's a poor ground.
Do you have colum or console shifter?

 

They used unlock when I open the drivers door. I have a console shifter. It's not that big of deal just to push the unlock button, my main concern is I have to open the passenger door to get the radio to turn off which is annoying. I just want it to work like it did when I got it. It also does not read that the drivers door is even open. I can do a system check and it says all doors closed even with the drivers door open. I reads the other doors when they open though

 

I would test the switch to be sure it's good.
Test for power at the connector and check for good ground at the connector.
You could have a wire going bad or broken in the door jam wire harness, its a known issue with these trucks.

 

I found this print from my 2013 manual, maybe it will help.
I'm not a strong print reader but a few things maybe.
The driver side door ajar switch ground wire is attached to the left side under the kick panel near the parking brake. (G200) The power door locks use G201 ground on the right side behind the kick panel near the body control module. I guess I would check that G201 also.
Looking at the print, I guess it is possible that one of the internal relays is bad in the BCM.
