Question about 2000 Mercury Grand Marquis

1 Answer

Will leaving the light switch turned on, while the car is off drain the battery? (Knob on the Dashboard, to the left of the steering wheel)

I'm having some troubles with my car. It wont keep an idol, but it still runs when in gear and driving. I replaced the battery but I'm still having problems. I always leave the light switch turned on and I'm wondering if that could be causing some problems? After driving for approx. 5-10 min depending on the weather, the car will keep an idol but it is very faint and you can barely hear it running. When it is really cold outside its extremely hard to get it running and when its warm it still has a faint idol and isn't running properly, but it is easier to get going. If you could give me any advice regarding this issue that would be awesome. Mainly I would like to know about the light switch draining the battery. Thanks!

Yes, any electrical device left running in car will drain battery, not unless you are running the engine for it will continue to charge the battery, regarding the idle setting issue, have a qualified mechanic check and adjust your clutch idle setting to fix your problem.

SOURCE: My battery light is showing

Here is a procedure to isolate a battery drain I found elsewhere and has already proved very useful several times.

Remove negative battery cable from the battery. Using a 12-volt test light, hook one end to the negative battery post the other end to the negative battery cable you just disconnected. The test light will glow or “light” if there is a drain. If the “light or glow” is faint, that is probably normal draw for the clock or computer. If the “light or glow” is bright, then there is a large drain. That should be corrected. Now start removing and replacing the fuses one by one until the light goes out; that one will be the circuit with the drain. ***Remember to hold in the button in the door jam for the interior lights.***

SOURCE: Engine will not idle and run when starting in cold weather

Have a mechanic take a look at your throttle position sensor and engine idle sensor. Make him manually adjust them as opposed to just putting in new ones. It may require that you have to have a higher idle than normal. Your underlying cause is going to be that I am sure you have a lot of miles on your engine.

No interior lights come on when doors are opened. Very dim instrument panel lights.


theres probably a switch off to the left of the steering wheel (probably some sort of wheel looking switch for the brightness)

Signal lights are not working


First of all have you checked the fuse? Then check the relay box for your signal relay, it is as follows.
To the left of your left foot, above the pull lever where you open your trunk. For the Flasher relay, you'll have to go behind the steering wheel column and take off that panel. Above the fuse box & to the left of the steering wheel there's a hollow rectangular box looking thing that's big enough to hold cigarettes. The hollow box has a lightbulb knob to the left of it. You can pry out the hollow box with a screwdriver to access the relay.

The dashboard lights on my 2005 highlander are dim, how can I fix this.


I belive the dimmer switch for the dashboard lights are located left of the speedometer. It looks like an odometer switch. Turn it to the right and that should make the instrument cluster and lights brighter.

I hope that helped. If you have more questions about this just ask.

What is wrong when the high beam lights doesnt go off? i have to disconnet the battery so that its not drained


While this will not "fix" the problem, it may alleviate you having to disconnect the battery. Once you have turned of the car, use the headlamp switch to the left of the steering wheel to turn on the lights manually. Then push the switch back in, and the lights will turn off. If the high beams will not turn off, it is possible that your multi-function switch has gone bad. This is a costly repair, and should be properly diagnosed by a certified service professional prior to replacement of the switch.

I don't know what I did to change the setting, but my interior lights do not come on when I open the doors any longer. Help!


There's a little knob on the left of the steering wheel. This knob can actually be pushed in and out. It turns to the left and right also, and can be turned off. I believe you turn it clockwise to turn the switch on for the lights to go on when you open the door.

The dash and interior lights dont come on, I have no manual


There is a round knob to the left of the steering wheel. This is a light switch. If it's turned to the left, the lights stay off. In the middle, the lights come on when the door is opened or the key is removed. To the right, it will turn the lights on anytime. By default, it should be in the middle (automatic) position. At the center of this switch is another knob that will pop-out if you push it. By turning the knob that pops out, it will change the intensity of your dash lights. Try popping the knob out and turning it all the way to the right. Then push it back in so nobody messes with it. Then make sure the light switch stays in the middle position. Hope this helps.
