Lighting control module 2001 Lincoln Town Car
Love my town car and want to keep it as long as possible.
It failed inspection because the headlights won't turn on. Garage thinks it's the Light Control Module. The part is discontinued, so I found one on Ebay. Hope to get it in a few days and will drop the part off at the garage in hopes of getting the car repaired.
Anyone have any experience with this part? Does it just need to be installed or are there a lot of complicated things that need to be done?

If the fuses and connections are good, then the 3 headlamp functions: low beam, high beam and flash to pass need to be verified as working or not. If none of them work then it is likely an LCM problem. Otherwise it could be the light switch or the multi-function switch. The test for the LCM is a scan tool. There are tests for the light switch and the multi-function switch.
The LCM is programmed for the vehicle and its features, less so for 2002 and earlier but there are more LCM features for the 2003 and up LCM. The normal procedure for a shop is to upload the existing LCM software to the scan-tool, remove the LCM and install the "new" LCM. A brand new LCM comes with a DTC already set and the installation of the software removes the DTC. If the LCM is from another vehicle then the software stored in the scan-tool is downloaded to the LCM and it should work correctly.
A new factory LCM is quite expensive but it will work. A used LCM may or may not work because of internal problems so you take a chance.
