My door ajar light and the dome light stay on whenever the key is on. 2003 F250 Super Duty Supercab 6.0 diesel. I have disconnected both door switches without success. Does my truck have a GEM, a VSM or an LCM that controls this function? Whichever one it is, where is it? Lots of misinformation out there on this issue from people who think they know but get contradicted by others who also think they know. Anyone know for certain?
Try jumping the plug on each door switch. Just pulling the plug off the switch doesn't do it.
