I have a 2000 Grand Marquis the overhead lights deep going on when the car is turned off, resulting in the battery going dead. If I take the light out (also the ones by the floor) will that take care
I took the overhead light out, didn't know about the floor lights. If I take them out will it take
care of the problem??Do I need to get a new LCM ?
get a NEW battery...clean the spot where the 1/0 cable connects to your chassis/ground...must be able to pull 300 cold cranking amps at least~ here and to the engine block (near the alternator) as well~
when you maintain the main ground connection any latent charge should dissipate (LCM, BCM, ECM...all)~
No, thats not the problem.
what's NOT the problem LindaL...http://www.youtube.com/watch? feature=player_detailpage&v=zdIKNnwEjIs
full disconnection of all things electrical did not reset this condition? is this what you are so rudely trying to tell me there?
It very well could be an LCM. The very best way to tell if it's an expensive Lighting Control Module is to hook up a scan tool that is capable of reading the LCM's inputs and outputs. You could try pulling all the bulbs - but that's not a cure and you could have other failures looming inside the LCM on top of that. There are other things that can bring a battery down: (Like judge_roy enjoys frequently pointing out) failing batteries and connections that fail, Alternators that keep the field energized after the car has shut off, fuel pumps that run incessantly etc. A couple of interior light bulbs should not bring a battery down overnight. Ever. Either the Battery isn't holding a charge OR the battery isn't being charged enough. I work on a Fleet of Crown Victoria Police Interceptors (same car - different badge). Frequently we see Alternators that stay on, AC clutches that stay on, Batteries that are WAY overtaxed by being repeatedly discharged and recharged (cop cars do that a lot). A typical LCM failure though usually involves the Headlights flashing on their own - not the interior lights. BTW - is the vehicle equipped with an aftermarket alarm?
