98 Grand Marquis - no headlights. I've replaced the LCM with a 'Cardone' refurb and installed a new light switch. All lights EXCEPT HEADLIGHTS work. What now?

I don't know what testing you have done? There are four fuses and a circuit breaker that supply voltage to lcm. Use a test light and check voltage on those circuits. Some are hot all the time, some go hot with the key on. The ground for lcm is black, check that also.

If you bought the Cardone "Band-Aid" and not the whole LCM unit. It may not fix it. HTH. -Jim

As a followup. Took the car to a reputable shop and the trouble was neither the light switch nor the LCM but a faulty Multi Function Column Controller. Headlights work fine now.
