One day it rained really hard, and since then my headlights will not turn off, no matter what I do. The dash lights and parking lights will turn off, but not the headlights. When I turn the Rav off, everything turns off except the headlights. I pulled the fuses so they wouldn't drain the battery. Some people were saying it could be a stuck relay, but I don't know where or which one it is. Has anyone ever had this problem before???????/
