Location of LCM (right bottom). 1. Remove screws, release locking tab, LCM inside.
To make sure you LCM is at fault here are some useful diagnostic tips: If your flash-to-pass function still works, but your headlights and high beams in the "on" mode do not work, then it's your LCM. The LCM just takes commands and process them. In the case of the high beams, there are two separate ways to switch them on and the flash-to-pass is independent of the "on" switch. If your high beams don't work in any method, then it may be the column switch. You can also verify the working order of your headlights by disconnecting the terminal at the bulb and sending 12 volts from the battery via a jumper wire to either of the light circuits (don't send 12 volts to the ground indicated by a black wire).
Not up to fixing your own LCM? Just want a new one? Well here is the scoop: You have several options.
1) Get one from Ford. Your dealer has them. The price ranges depending on how good of a negotiator you are. They retail for $511.07, but your dealer has discretion and may sell you one at the cost price, as low as $389.00. Online Ford parts sites, such as http://www.teamfordparts.com/ could be an even better deal if they list your part number. The LCM part numbers are 12 digits long and start with the year of your car, for example 5W7T-13C788-AB. This LCM would be for a 2005 Crown Vic. They are on a white tag on the bottom of the LCM.
2) Get one from a salvage yard. These are much cheaper (~$100), but they may already be on their last legs. Some salvage yards may sell rebuilt modules.
3) Go shopping on eBay. Two types are available on eBay. The first are just like the salvage yards, LCM's of questionable serviceability (think of all those taxis out there), and similar prices. The second type are people who use your LCM as a core and sell rebuilt modules. Here is the email of one such type: digitalguy_1@charter.net This source specializes in rebuilding automotive "black boxes". They come with a lifetime guarantee. The cost is about $100.
You should know that your are not alone and that faulty LCMs are very common issue with 2002 and newer Panther cars. It's not so much a matter of if, but when the LCM will fail.
Next: How to save your LCM and prevent early failure.
