Mercury - Grandmarquis :: A/C Malfunction - Buzzing Sound From Under The Hood - Brake Warning Light Keep Coming On
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.
Mercury - Grandmarquis :: 2000 - Intermittent Loud Humming Noise
A loud humming (sounds like a compressor). I can place the car in neutral, the engine revs up, and humming will stop. I have to repeat this action for the first 30-45 minutes from start of drive time.

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.
View 1 RepliesMercury - Grandmarquis :: 1998 - Loud Squeaking Coming From Front End Shocks
I just noticed that my Grand Marquis recently started to squeak rather loudly coming from the front end shocks.. Think its coming more from the passenger side.. Now we've never changed the shocks since we've had the car so I'm fairly certain it's going to need some new shocks. But could this also be because the lube has dried out on the suspension ?. Doesn't affect the drive but it sure is annoying driving around with the squeaking...
View 4 RepliesMercury - Grandmarquis :: 1997 - Interior Lights Staying On / AC Making Tapping Sound Behind The Dash
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...
Mercury - Grandmarquis :: Electrical Malfunction - Power Door Locks / Trunk Release / Rear Defroster Stopped Working
The following have stopped working (at the same time if I remember correctly): power door locks, power mirrors, power trunk release and rear defroster. We are also getting a tire pressure fault warning when the tire pressure is ok. As far as other items located on the drivers door, the power seat adjustment and power windows are still working. I checked every fuse in the interior box and the the rely ant fuses unde the hood. I exchanged the big, square, grey fuse for the rear defroster with the one for the starter and still no luck with that issue.
View 5 RepliesCaravan/Voyager :: 1998 - Whistling / Humming Sound Coming From Rear Of Van
It is as an electronic whistle/humming. The sound is coming from the rear of the van, and no, not when it's moving, even though it still does it when moving. The only thing I can think of would be the fuel pump. Because It's loudest just before the rear tires, not after them. My fiancee has heard it twice now, when she first heard it, I didn't, but this last time when I heard it, I also noticed that the gas gauge was reading just below 1/8 of a tank.
Would like to know if it's the fuel pump or something else I'm no thinking of. And if it means I have to replace the pump.
Golf/GTI VII :: Knocking Sound Coming From Rear On Every Tire Revolution
I hadn't driven my new GTI (DSG w/PP) for the last month. It was regularly started but not driven. Took it out today and noticed a knocking sound coming from the rear that could be heard every tire revolution. Distinct sound, not metal to metal as if a caliper had hung up. Noise in forward only not reverse. Nothing interfering with tire revolution. Needless I'm not driving until I get it checked out. What it could be?
View 2 RepliesMercury - Grandmarquis :: Won't Start Sometimes
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.

When I'm driving low speeds...say under 40. there is a random but frequent rubbing sound coming from the front passenger tire. Previous my driver side coil over blew out and it was replaced by VW and they raised the car. After about a week i noticed the sound. The car also shakes between 55 and 65...so i'm assuming it's a balancing issue. But can't figure out what the rubbing is....ball bearing maybe?
View 5 RepliesMercury - Grandmarquis :: Vibration When Traveling At About 60 To 65 Mph
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.
View 6 RepliesMercury - Grandmarquis :: 2007 - A/C Is Not Cooling
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.
Mercury - Grandmarquis :: Will Not Start After It Gets Warmed Up
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.
View 4 RepliesMercury - Grandmarquis :: 2002 Will Crank But Never Turn Over
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.
View 4 RepliesMercury - Grandmarquis :: CEL Blinks On And Off In Intervals And Seems To Be Missing?
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???
View 8 RepliesMercury - Grandmarquis :: 1994 - Won't Accelerate Very Fast?
We have a 1994 Grand Marquis. Sometimes when driving the check engine light comes on and suddenly she doesn't want to accelerate very fast at all. If you do try to hit the gas, it sounds like the engine speeds up but there is no change in acceleration. It is also hard to get to/over 50mph. If you pull over and rev the engine a few times (slowly) there is an audible click from somewhere inside the engine. It will happen a few times and then the car seems fine. Inevitably the issue will come back a some miles down the road.It doesn't get driven every day and so far we have not had the light come on when we are near anyone that can read the error. Also, it resets and is not on if you turn the car on and off, even if the problem persists. It only comes on while driving (though it will stay on if put into park and left running). Oh, and possibly related, it seems that the air that is put out form the defroster is very damp when this happens (sometimes).
View 3 RepliesMercury - Grandmarquis :: Buzzing Noise Under The Hood
Several minutes after I start driving in the morning, my car starts making a strange noise under the hood. It sounds like a motor running, or a strange buzz. After a few minutes, the noise stops stops. When it does, and if I'm stopped at a light, my engine jerks one time. The engine actually shut off one day, but I could start it right up. It does this once during the trip. The speed of the car or engine has no effect on the sound, but it stops if I turn the car off. If I restart the car, the noise does not return.
