Well first to start off i have had this issue since day 1with my truck. The dome lights stay on and door ajar light does too. WD40 already been done in latchs. I replaced all 4 switchs and the 2front latchs with the same issue this was also 2 years ago. Now i wanna sell the truck and get something new so its time to fix it. The odd thing here is if you open both front doors the lights go out. Soi tore all the door panels off checked all the wiring. Im getting good resistence through all the grounds and power to the switchs. I figured since all was working right the VSM was bad.Well i was wrong then ford wouldnt fix they said it would cost too much and cant gurenntee a fix!! Brought it home then checked for power going to the vsm. Getting B+ with doors open and 0v with doors closed as should. Also i load tested the circuit all good. Im honestly stumped now. With no wiring diagrams i cant figure it out. Also ford wont give me one. I have been talking with cheezit who is very knowledgealbe since he works for ford i also work for navistar and im stumped. Someone have a diagram for this? Or ideas?trucks a 2002 f350 larietcrew cab
