My 98 3L OHV Taurus station wagon back up lights wont work. Checked fuse, ok.
Removed tail gate inside panel to access back up lights, both bulbs good.
Checked both bulb sockets for 12vdc power with ignition on & shift lever in
reverse. No DC voltage present. Checked the wire continuity between both bulb
sockets and there good. The socket wire to ground is also good. I even went
further and applied 12vdc to the interconnecting back up wire on the tailgate
and both lights work fine. I am unable to check continuity between the tailgate
backup light wiring and the fuse panel without proper wiring diagram. Can anyone
give me some help in troubleshooting this problem. More so in locating the
different areas of the wiring such as backup switch location so I can isolate
on the wiring Diagram I see:
from the fuse (#6) power goes to pin 9 on the Digital Transmission Range
(DTR) sensor and if the DTRS is good, and the selector is in reverse,
power comes out on pin 11 and goes (eventually) to that splice you found.
