08 Ram 1500 quad cab door open light and interior lights will not go out

[trooper1954]

HI Guys, brand new here with my first question.
I have an 08 Ram 1500 quad cab in which suddenly the "door" open light stays illuminated and also the interior lights stay on. Checked all doors...secure. Checked rolling switch for interior lights....working properly. Sprayed WD40 on all door locks and open/closed door several times...no joy. Disconnect battery to reset computer....no joy.My question is if this is a door lock assembly problem, how do I determine which door is at fault so I can replace it? The door light comes on as soon as the ignition is on, so I don't see how to troubleshoot which door?
Any and all help would be appreciated.
Thank you

You should pull the "wire boots" at all doors and tug on the wires to make sure none are broke, that's where I'd start.

What he said but start with the drivers door as it is probably used the most.
