daughter recently purchased 4wd Eddie Bauer explorer. After fixing many small irritating issues and her driving it for about 2 years now it seems the bkup lights are no longer working. By moving the shift lever around a bit the lights will actually come on but not stay on. I can't seem to find a separate switch for the lights on the trans and do not have a service manual. I have never had any experience with Ford products other than Mustangs. Mostly GM stuff. There seems to be a what i call a range sensor at the end of the shifter cable with a harness coming from it. Do those go bad and is the switch a part of that sensor? She has taken it to a few local so called mechanics before bringing it to dear old dad, me. I was shop mechanic for GM dealerships for years. thanks for help Ron
