2000 ford crown vic, park lamps come on, but no headlamps

Usually it's a case of the regular headlights not working while the high beams (brights) still work if you hold them on while driving, but if you have a 1999-2011 Mercury Marquis, Mercury Marauder, or Crown Victoria, and your regular headlights and or tail lights don't work it probably is your LCM that used to cost around $1,000 to repair.

The good news now is that Ford just finally extended the warranty on your LCM (Lighting Control Module) for free - both parts and labor and will install a new one for free! Ford has extended the warranty to 15 years/250,000 miles. THIS IS NOT A RECALL! They do not advertise this.

Your regular headlights must be inoperable in order to get a new LCM on this new extended warranty. It must be done at a Ford Dealer and the fix is free. Call your local Ford Dealer and tell them you need to make an appointment because your headlights don't work and that Ford has extended your warranty on the LCM.

They may act like they don't know what you are talking about, so tell them it is the Customer Satisfaction Program 14N01. Have your car's Vin number ready as they will ask for it. You don't have to be the original owner. If they still act like they don't know what you are talking about ask to talk to the manager or tell them to call Ford Motor Company and ask them, or you can call Ford yourself.

We had ours done at a Ford dealer in August of 2014 in Scottsdale, AZ but first they checked out our LCM first to make sure it didn't work. As soon as they found out it didn't work, the installed a new LCM for free under the about new warranty called "Customer Satisfaction Program 14N01".

It sounds like you might have a bad headlight switch. I've seen alot of them go bad. I would check the headlight fuses.
