before we get into the next test/s

With the engine off and the key still in the Ign switch does the chime work when you open the doors

Also see if the chimes work when the key is removed but your headlight are on and you open a door

 

[Bedrck47]

Just sent you a private message

 

[Bedrck47]

did you check to see if the chimes work see post #27

Im following this as well, my radio wont shut off and my interior lights dont turn on when the door is opened, no key chime or lights left on chime, no door ajar warning. From other reading I thought it was the door switch, I havent replaced mine yet but this seems to be more indepth testing

 

[Crazy_moh]

No door chimes.

With the engine running do you get a door ajar warning when you open a door or the lift gate

Hey take the drivers side sill plate off and get to the wires that run in there
Find urself 3 purple wires that run into a union going towards the front of the truck
The union will just look like heat shrink .
Now when u find it you'll have 3 wires going towards the rear of the truck and at the union 1 running towards the front .
In the union the wires might be corroded
I had some of the same symptoms and that's what I found .
Repaired that and everything works as it should now
Good luck

 

[Bedrck47]

Thanks for that suggestion I will pass it along to the OP

 

[Bedrck47]

UPDATE

The OP sent me a e-mail this morning and informed me that,

"It was the wires I found cut them and fix them and it works like it should"

Bringing this back from the dead.

Crazy_moh, DOHC-Bird, anyone else

Were these wires under the metal guard thats under the drivers sill plate? In the wire loom underneath? If so, I assume you had to crack open the loom.
Or were they in front of the metal guard behind the drivers kick panel?
I have the exact same sypmtoms, Im just trying to pinpoint the same purple wires so I can check mine.

 

[Bedrck47]

this is where you want to look the wire are in the wiring loom under the sill plate I do have pictures of what you would be looking for and will post them when I can find them again
