I am new to this site, and it's great. I have a 2003 Expy. that has some wierd issues, you will be driving along everything fine then the interior lights come on,the door ajar light comes on and the annoying ding ding. all doors are firmly shut. It will even do this while parked in the drive-way with no one around it. My kids think it's haunted, do I call the Ghost Busters or can someone here help. I have tried to squirt WD-40 into the doors to wash stiff grease on switch pins, but no help.
