I am terrible with electrical and before I go on the hunt for the problem It would be cool if someone could help diagnose what the problem is cause I have hidden all my electrical and it isn't easy to get to. I just don't understand electrical as well as I should. but the fan wont turn off when the key is on, it just recently started doing this, I'm thinking relay? here is the instructions to the fan relay i used if it helps
