Mercury - Grandmarquis :: 1997 - Interior Lights Staying On / AC Making Tapping Sound Behind The Dash
Oct 17, 2011
I've been having a problem with some of the interior lights staying on and killing my battery each night. The lights that stay on are the climate control lights, gear shift light, and the lights on the door for the windows and locks. Every time i have to crank up i have to get it jumped off. If i pull the fuse out for the tail lights i no longer have the problem. I was wondering does it have something to do with the lighting control module or maybe the headlight switch.
I also have been having a problem with the a/c making this tapping sound behind the dash. Even with the a/c off you hear this constant sound as long as the car is on. I have no clue what is going on...

I have a 2001 Merc. Grand Marquis with a digital dash. The problem I am having is that the speedo displays 0 intermittently. What may be causing this? The cruise control will still work if I set it when the speed is showing.

This is my Dad's car. He took it to the garage twice in the past six weeks to resolve the problem. The first time, Bill the mechanic said that he thinks it is a bad sensor, and he replaced the sensor, but at that time, it didn't start when the engine was cold. Then immediately after taking it to the garage, the car began to not start every once in a while (in the middle of a trip) when the engine was still hot. And so, my Dad took it back to the garage and Billy replaced the fuel tank shut-off/reset button device in the trunk near the driver side hinge. But guess what, the problem still continues.

On first start of the day (engine cold), the transmission emits a siren-like sound similar to a hydraulic pump air-bound or cavitating. Sound disappears after first 1 or 2 miles of driving. Does not repeat during the rest of day when engine is warm. Repeats again at first start each morning. Ford dealer check of no value since mechanic could hear nothing with engine warmed up.

So today while driving my '98 Mercury Grand Marquis home I noticed a leak was coming from behind the rear right tire.. Or I'm guessing it's a leak ? But it's kinda like a grease substance and it sure does smell bad! It's all over the backside of the tire and muffler (probably why it smells).
While driving it there is a low humming sound? Best way I know how to describe it and if I go over 60mph it gets increasingly louder.. After looking up some forums online I came across that it could be a possible wheel bearing or maybe a bad axle problem?

I'm having several problems, and I'm wondering if they are related: Sometimes the heat/ac/vent blows on the windshield instead of where they are supposed to be. Occaisionally it works at first, and then changes after a few minutes to blow onto the windshield.
Sometimes I get a buzzing sound under the hood. Usually when I'm stopped, but sometimes while moving. The car idles high when this happens. If I tap the accelerator, this usually stops the noise and the idle drops to normal.
This morning, the brake warning light kept coming on while using the brake. The fluid level and pedal are OK, and the car stops OK. Then the buzzing sound came on, the engine light came on, and the brake warning light went out at the same time. The brake light hasn't come on since. The scanner tool indicates the IAC was running too fast.

2000 Mercury Villager tail lights stay on: This car is supposed to have a tail light relay. But I don't know where it is,accept 'main junction box' but I don't know where that is and which component would be the tail light relay.

Had this 2015 Prius 4 four a couple months. Today, all of the interior lights, (the two in the front, plus the dome light) are all staying on. The switch in the back is in the middle. Messed with it. Didn't work.They are staying on, after locking doors and significant time lapse. Is there a switch or button that would do this?

I have a 2006 Accent and recently the interior lights have gone dim and the switch to adjust them does not make them brighter nor dimmer, why this has happened? I don't usually have it on the brightest but not the lowest either and now it seems to stay on the lowest setting.

My interior lights just started staying on intermittently. Seems like the front passenger door. I'll have to pull the panel and lube the switch.

Interior lights are sometimes staying on for 30 minutes after all doors have been closed. Thought it was the back hatch, but now seems to be random. I've cleaned the latches and lubricated with no luck. What else could be causing this?? A relay, computer.

A little history first. 1998 F-150XL ... We bought this truck in 2001 and other than some random electrical issues we love this truck. The first thing to go bad was the was the interior light staying on even with the door closed, no big deal I just removed the bulb, the next thing to go bad was the instrument cluster except the speedometer, not too big of a deal just keep track of the mileage so you don't run out of gas. The next problem was randomly not starting like it lost its ground, the lights on the dash would be bright until you hit the starter then the lights on the dash would go dim and the starter would tap like it had no ground. Wait a few minutes and it would start again and it would be a year before it would do it again, until now!
Drove to town came back out did it again except this time would not start again. We pulled the starter switch it was good, replaced the clutch engagement switch on the clutch pedal, no good. Decided to pull it home, tried to pop start it, no dice. While pulling home all the sudden everything lit up on the dash and it started like a champ, drove it the rest of the way home and it wouldn't start back up. Since then I have put in a new battery, new battery wire ends, took lose the ground on the firewall and starter and cleaned them with no luck. I can get the lights to come up bright on the dash again, but as soon as I hit the starter all goes dead again. I am at a complete loss where to go next?

Although it starts most of the time, about two times a week it will act as though it's going to and won't. We had it in a shop for about 3 weeks and the mechanic said it started every time for him. When I got it back, within a few days it would not start. I try after about an hour and it starts. He ran diagnostic tests and nothing showed up. I want to give this car to my teenage granddaughter and I can't have this problem.

Getting slight vibration when traveling at about 60 to 65 mph. Tires are almost new and had them rebalanced about 2000 miles ago. Shocks are less than a year old. Wondering if it is a wheel balance problem or possibly an alignment problem.

How the HVAC system on the big Merc and Crown Vic are controlled. One answer says it's vacuum, another says it's electrical, another says electronic via the BCM. Which is correct? Does it have an electric servo to move the flapper door(s) like the Taurus I'm familiar with? Even the BCM has to have something to tell to move the flapper doors.
In the car I'm looking at, the lines into and out of the evaporator are cold when A/C is selected and the compressor clicks in. That makes me think the issue is with air direction. All I have to do is figure out why.

Have a 2000 grand marquis that will not start after it gets warmed up. Recently had two occasions where after driving for about half hour and it's shut off, it will not start. Cranks good, but will not start. After it "cools down" it will start. Have had it to my mechanic and the dealership. They can't find anything??? They say it has to get worse before they can make it better. They don't want to start throwing parts like fuel pumps at it.

My garage was struck by lighting this morning, and about two hours later I heard a very loud snap coming out of the vicinity of my garage. The snap was so loud, my ears were ringing. When I went to start my car (2002 Mercury Grand Marquis), it would just crank, but never turn over. The interior lights and trunk lights did not work, so I replaced the battery thinking that the power surge could have affected the electrical system of my car...and I needed a new battery anyway. With the new battery installed, all of the lights once again work, but the car still will not start. The voltage meter is low and it never runs low. I tried resetting the fuel pump shutoff, but it was never tripped and I can hear it pumping when I turn the key on. Is it likely that the mechanical failure is due to forces outside of electricity even though this car has never failed to start, or could the electrical surge have affected something else (alternator, fuses, etc.)?

My windshield wipers do not park all the way down. The left one is up at a 5 degree incline, the right one more like 15 or 20 degrees. I went through a car wash today, and the air dryer blew them all the way to the left, and back to the right a little. I turned them on and back off, and they returned to the original position (5 and 15 degrees). Car is 2002 Grand Marquis LS.

My '03 Grand Marquis "shudders" when I accelerate, especially up hills. It feels like it cuts in and out momentarily, shaking backward and forward. Here is what I have had done, based on mechanics' advice: replace spark plugs, replace fuel filter, clean throttle body, clean mass airflow sensor. It still does it after all this and I am stumped.

Today while driving my 03 marquis the check engine light started blinking, after a few blinks I noticed it stopped . But a few moments later it started blinking again then stopped, so on an so on. I also noticed that the car had a immediate loss of power and it seemed like my car was missing, and while trying to give it gas it would shutter. It never killed on me but I can tell it ain't running right. A friend of mine told me to push the brake down while car was running an in drive, an give it gas like you was going to,"power brake it". I did, and instead of it power braking it just shook forward as if it only had 4cyl instead of 8cyl. then my buddy said its a bad "coil", no how he knows that idk. But is that true or what it might be???
