HELP! truck doesn't know when drivers door is open
 

just like the title says, the truck doesn't know when the drivers door is open. it always thinks it is closed. when I shut off the ignition and open the drivers door, the radio still plays. I have to shut it off manually. the passenger door works correctly like it should. My first instinct was a broken Pin switch, but there is no pin switch to be found. any pointers would be great!

Spray some penetrating oil in the door latch. The switch is probably stuck.

Even with the door pin broke the radio and all accessories should kick off after 10 minutes.
