you are probably on the right track, its located directly behind the fuse block on the driver side ,remove four nuts and you can work it out the back side. some folks have said moisture gets on the gem causing it to malfunction. personally, I have never seen moisture,but it makes sense when wd40 seems to at least temporarily fix the problem. hope it works for you.
