Door ajar warning will not come on when the door is open

[SandawgK5]

So I have found all kinds of info on what to do when the ajar light stays on, but my problem is the door ajar wont come on with the door open and the radio won't turn off until I open the passenger door.

I did the WD40 thing and it didn't work so I pulled the switch and cycled it by hand and still nothing. I checked the switch with a multi-meter and got an open with the switch not pressed and about 30 ohms resistance with the switch pressed down.

I then checked for voltage at the plug and got nothing from the yellow/black wire.

I checked resistance on the yellow/black and got open and as expected I got ground on the black wire.

Has anyone had any experience with this? Should I see a voltage at that plug with the acc delay relay energized?

Thanks

Also everything else works on the drivers door except for the head light on warning. I had the headlights on (not in auto) and left them on when I turned the truck off and did not get the idiot bong when I opened the door.

I got it figured out. The previous owner had cut the yellow/black wire from the keyless entry box, which also provides voltage to the door ajar switch and spliced in a relay for an alarm or something.

I took the relay out because it went nowhere and had the wires just dead eneded. unknowingly I disconnected the relay and did not realize what I was disconnecting. I soldered the yellow/black wire back together this morning and low and behold the door switch works as designed.

Now I am just waiting on my new switch since I broke the little tab of the switch and it wont stay in the door latch anymore
