Ford F-150 Electrical Problems

Hello Again, I figured that as long as I was here, I'd share my other problem. A while ago, my wife drove my truck and when she was done she asked me why the turn signals didn't work. I went out to the truck, tried the turn signals, and everything worked fine. After some experimentation, we found that as long as the steering wheel was in one of the top positions, everything worked fine. However, if we adjusted it to a lower position, the turn signals and the brake lights stopped working. Since I drive with it in the top position, I didn't worry too much about it. Over time, it got tot he point that only the very top position worked. And now, even that is starting to flake out on me. It works most of the time, but the left turn signal seems to be having problems. Also, the electric door locks will not lock or unlock the passenger-side door. Travis
