I’m new to the site and have a few electrical issues on my 2008 ranger sport 4x4. I had my clutch recently replaced and when I got it home I noticed that my back up lights didn’t work and my 4x4 will not engage. Another little quirk is that when I park it and I leave it in reverse with the key off my heater fan pops on. I shift it in to any other gear and it goes off. It’s been at the Ford dealer for over a month. They thought it was the fuse box. It was getting rusty and corroded so they replaced it and I still have the same problems. Supposedly they’ve been contacting the Ford hotline to find out what else to try but I haven’t heard back in about a week. Any suggestions I can give them would be much appreciated.
