First time I had the "door adjar" indication on the dash....and interior light staying on..... I had the van FULL of kids for a church outing..... They got a kick out of me running around the van trying to figure out which door was not closed properly. Having ALL the doors closed properly is kind off importand when you have the van full of other peoples kids.
The most likely cause is a door sensor not making a good connection.
I was lucky with the WD-40.
