I have a 2004 Lincoln Navigator with HID lights. The Driver side low beam stopped working so we bought new HID light that came with a new wire. It will Not turn on. We checked Fuse Boxes as well, they are fine. When we turn on the lights you can see the light power up and flicker and then turn immediatly back off. HELP!

Do you
have the same problem?

This is what they do when the light ballast is bad did you replace that as well? Here is a guide and some diagrams so you can test for power and go from there.

I have a 1999 Navigator. The headlights quit working. The parking lights work but will not turn of with the switch unless I re-start and turn off while engine is running. All the fuse's are good and the bulbs were replaced.

For the parking light, there are 3 things that can cause it :

1. Faulty light switch.
2. Faulty parklamp relay.
3. Autolamp control module is not cutting off when ignition is turned off.

When problem occurs, to test if it is the switch, disconnect switch connector and if light stays on, it is not due to the switch.
Unplug the parklamp relay and connect a test lamp across either Tan/White and Light Green/Yellow wire and if test lamp lights up, the Autolamp Module is at fault.

Is vehicle equipped with Daytime Running Lights?

I can not see the wires and I do not have a schematic to show me what color wire is for the plugs position.

Is vehicle equipped with DRL? I needed it to get the correct wiring schematic.

You need to get underdash and and possibly requires removal of the steering column and underdash covers to get to the wires.

Here are 2 different schematics, one with autolamps and the other without.

If it is without autolamps, the most likely fault would be a bad light switch.
