Strange Expedition Problem...
 

Hello all, new here but have been reading posts for a while now and like the site!

This morning I went to get some gas for my 2000 Expedition 5.4L after a huge 60+mph rain/thunderstorm and when I got into the truck, I noticed the blower motor was on. Good thing I had a new battery is what I was thinking... For some odd reason it now operates without the ignition having to be on. I can turn it off using the switches, but why all of a sudden does it work without the ignition switch on? Please help!!!

Thanks
