It's a bad door sensor. You need to figure out which door. For me it was passenger/front. No amount of spray would work. I looked online and the sensor was $45. The heck with that! I unplugged the sensor and jumped it. Basically take some wire about 2 inches long. Strip both ends. Insert into socket the door sensor was plugged into. Tape everything up pretty good so it doesn't come loose. Put the door back together and you're good to go. Only downside is lights don't come on when passenger opens the door. Oh well, I can live with that.
