Asked by GuruCRSZ6 Mar 03, 2019 at 11:00 PM about the 2005 Ford Crown Victoria Police Interceptor

Question type: Maintenance & Repair

All lights work on the front and interior of the vehicle, but all the back lights all don't work. No hazard, tail lights, break lights, turn signal. They all don't work. Checked the fuses. Can someone help with what this could be?

Have you traced the wiring ? There my be a loose wire or a bad ground stoping the connection reaching the back end.

Had the same problem with my 20003 PI71. Issue was the LCM (light control Module) located under dash. Ford has a recall on the LCM but you have to take to the dealer. The closest ford dealer to me is 1oo miles so I found a band aid auto Zone sells for this and it involves unplugging the 2 sets of wires entering into the back of the LCM, then plugging in the Auto Zone adapter into the LCM and then plugging in the 3 sets of wires into the adaptor. This all made for a really tight fit but it worked. Only down side is now for some reason my horn no longer works.

If you have checked all fuses then strike and or turn and off emergency flasher switch rapidly, repeatedly. If that doesn't work its probably your light control module is bad.
