go though each door while the truck is running and see which door doesn't ding when you open it. i had the same problem and it was my driver's door. 15 dollar sensor and i was good to go.

Common problem with both the Expy's / Navies / F-series trucks.... Door jam switch gone bad.

Here's a previous thread on it .....

Not one of the door dings when there opened so does that mean all of them are bad?

No. Turn the ignition key to the accessory position and turn the radio on. With the radio ON, turn the key back to the OFF position and open the doors ONE AT A TIME and see which one DOES NOT turn the radio OFF when you open that door. The one that fails to turn the radio OFF has a bad door sensor. The sensors are different between the left and right side of the vehicle, so make sure you order the correct sensor(s). It's typically the driver's door. But on rare occasions you may find the others defective too. Once you get the door latch to a location where you can remove the sensor, a quarter turn counter clockwise releases the sensor. For future reference do not spray WD40 or any oily lubricants into the door latch. The sensor sits at the bottom of the latch and all the oils and lubricants attract dirt and grime into the sensor's plunger and cause it to get stuck.

I believe the rear doors will not cause the radio to turn off I could be wrong

That is correct. The front doors when opened, should kill the radio. My mistake for leaving that out, thank you.

Yes that is correct. That's why leaving it running and open one door at a time is the best way to diagnose it.

Also the door chime may not work if they have been disabled
