Check under the hood for the big fuse box. Pull the relay that is indicated for the headlights. It is getting hung up by welded contacts. Replace it!

SOURCE: Stero killing battery while car is shut off.

Usually car stereo's have two wires that supply power, aside from the ground. One has power all of the time, for your memory and clock. The second is for when you turn the ignition key on, to allow the stereo to come on. It sounds like you have a power wire going to the the wrong one.

Headlights wont turn off. I had to remove battery cable to shut them off

Suspect a shorted daytime running light module. Here is where it is located. You can unplug it and will have to use the headlight switch for the lights to come on. Remove the plastic clips to release the cover and remove the cover. You will then see the module bolted to the rad support

1997 gran marquis will shut done while driving

The biggest suspect I can think of is the ignition switch, as it also controls the electrical as well as the engine. If it happens again then turn your lights on (manually) and check if the headlights are on. If they are then there's a good chance it's ignition related. Check all fuses and make sure the fuse box itself is well grounded if the headlights do not come on. Make sure all battery connections are clean and tight. See if there is a engine code to give a greater clue.

I have a 97 marquis and the headlights wont turn off whether the car is on or off and its killing my battery

Until you get as fix, unhook one of the battery cables each time you
stop the car, and hook it up again when you are ready to go somewhere. Sounds like it might be a broken headlight switch.

97 Merc Grand Marquis wont turn over after sitting for the winter. Battery is good. Ran great until sitting for 2 months.

The starter is probably just hung up, I would recommend that you gently tap on it with a rubber mallet, or the wooden end of a hammer.

How to reset 1994 Grand Marquis computer

easiest way is to reprogram with a scan tool

however, you can reset many of the functions by disconnecting the battery
and while disconnected, turn on your headlights

yes... turn on the headlights with the battery disconnected

obviously the headlights will not work but more importantly, any energy stored in the computer will disipate when turning on the headlights... this may clear many of the stored data in the computer
