1996 Mercury Grand Marquis LS, 183000 miles. Car loses all power, randomly. Then starts up in about 3 seconds.
The following repairs have been done: crank sensor, cam sensor, idle control valve, ignition switch, all ground wires checked. There are no computer codes generated. This has been going on for over a year. Has been checked by dealer and three other mechanics.
THE PROBLEM: The Power Locks, Trunk Release and Power Windows Lock on my 1998 Mercury Grand Marquis have stopped working altogether. They don't work with either the key remote or the actual control panel in the car itself. So the only way to open the car or trunk is the old fashioned way, with the key. SO FAR...I've tried replacing the fuse - a 20 Amp CB - on the fuse panel, but it had no effect. What's my next step?
A LITTLE BACKGROUND: Recently a different key remote stopped working for this same issue. I tried replacing the battery in the key remote, but it had no effect. So I began using my spare key remote and it worked fine for about a week. But during this time the control panel in the car still worked properly. Now nothing works. Not sure if the other remote's issue was related or not to what's wrong now.
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 RepliesMy mercury Monteray 2004 model, suddenly loses power while driving. This has happened both on the freeway and on the local roads. I then have some how driven it to the shoulder. After stopping for couple of minutes when I restart the car it works and I have been able to drive it. I have taken it 3 times to the dealer and he has not been able to identify the problem. I am extremely scared of driving the vehicle. We even had flight recorder from the dealer on the vehicle and recorded the incident 3 to 4 times and still the dealer has not been able to figure out what the issue is. They say that they have tried several times and have not been able to recreate the issue. They say that they have tried to recreate the issue with a computer attached so they can record the issue when it occurs. But apparently they have never been able to recreate the issue. Other wise the van is in excellent condition. What could be the issue? We have not been able to use the van for over 6 months and do not know what to do with it.
View 3 RepliesAlthough 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.
View 10 RepliesGetting 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 RepliesHow 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.
View 4 RepliesI have a 2006 Nissan Murano with 122,000 miles on it. It's been a good car, but recently it has had a few episodes of losing power. Here's an example:
I had been driving the car here and there all day, and in the afternoon I swung by my mom's house to pick her up. When she got in the car (I had just been idling while waiting), I went to make a U-turn and the car outright died. I started it right back up and was able to drive to the end of the block before it lost power. It didn't die this time -- the engine was still on -- but all my electrical components went out -- radio, dashboard lights, AC -- and I couldn't get it to go more than 20 mph. That was flooring it. It wasn't giving me a high-pitched whine, just a low hum like it was trying really hard to go but couldn't. I turned it around and barely made it back up the hill to my mom's to park it. It just had no get-up-and-go. An hour or so later my dad came home and checked it out and of course it was fine. Started right up, drove fine.
This has happened twice since, both times I was driving on the freeway when I felt the loss of get-up-and-go and saw the electrical components go out. These times it only lasted maybe 10 seconds, after which it just came back to life in the middle of driving and drove fine the rest of the day.
It makes me think there must be some sort of loose connection somewhere? I'm frustrated by the issue because it's not repeatable. So when I took it to my mechanic, they said they couldn't find anything wrong. They hooked it up to a code reader and nothing came up, and they drove it around and around and it was fine. The idea that it could maybe strand me on the side of the road (I drive my kids around all day) scares me, so I've swapped cars with my husband for the time being. But I want my Murano back!
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.)?
View 19 RepliesMy 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.
View 3 RepliesMy '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 RepliesToday 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 RepliesWe 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 RepliesSeveral 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.
View 4 RepliesWhat would make a 2000 mercury grand marquis stall when turning right? I turned the key and it started running again. Check the engine light and it was po442 which is the emissions leak.
View 3 RepliesSo earlier today when I tried to start my car it wouldn't start! I tried cranking her over twice and I got nothing. The battery gage needle didn't move when I tried starting her up the few times. What's weird is that I took my other car (parents) out to run the errands I needed to run and when I got back I thought to myself "well maybe the battery is dead and needs to be jumped" that makes sense right? So as I pull up next to my car I decided to try starting her one last time and when I put the key in and cranked her over she started right up! Not a stutter or anything! So I'm left with the feeling that maybe it could be a failing alternator ? Or possibly a loose cable or something ?
Btw the car is a '98 Mercury Grand Marquis.
Here's a little about the car before I start about the problem because my car is very custom. It is a 84 pontiac trans am with 305 H.O. code G engine V8. It was completely redone about three years ago and runs great. We did delete most of the computer control stuff and emissions. We now have a vacuum controlled distributor instead of the original computer controlled one. There is no engine light to check now and here's why. We have converted the car into K.I.T.T. from Knight Rider, so the entire gauges on the dash have been turned into digital gauges including the speedometer.
The new gauges run off of the same power that the old ones did. But we have added a separate switch to turn just the dash on for car shows so we don't have to turn the key on. it goes to the fuse for the computer/ gauges and a few other little things. We also have two lcd screens installed and a computer.
Now for my problem. The car still runs great no issues with how it runs or sounds engine wise. It doesn't matter if it is cold,hot, wet, or dry. I can go down the road and all of the sudden all the power to the dash will flicker off and on. I usually lose my speedometer then and don't know how fast I'm going. It will not power up fully unless the car is started normal. The car has to have the gas pumped a few times before starting normal. No biggie. Now, the entire dash will flicker and sometimes when it goes out in the middle of driving, the car just dies. About a week ago everything lost power. No headlights, flashers, interior lights or power to start the car. After a few minutes, one by one the things starting to work.
Interior lights first, then headlights and five minutes later the dash lights come back and the ignition has power again.Went to town the other day and drove for an hour and no issues at all. Today, the lights flashed on the dash, get home, shut the car, turn it back on and fine. Waited a while and had the door open. Shut the car off and it lost power to the ignition. Interior lights were on but no power when you turned the key. The radio would flicker on/off real quick, but no power to the dash or to start the car. Turn the key to acc mode and the radio works but again no power in the on position to start the car or turn on the dash.Now, we can turn on the extra switch to power the dash and it will come on but not when I turn the key.About ten minutes later of just sitting and the car was back to normal. Turn the key and power was back and started right up.
Here's what I've done. Battery and alternator checked out fine, checked all ground cables to firewall, starter, etc, looked for lose wires or melted wires, took distributor cap off and check that area, clean battery cables wires, looked for any corroded or dirty wires, made sure all wires were tight. I even went under the dash and put in a new ignition switch ( I don't ever want to do that again. That was a pain in the neck and I really mean in the neck) Still the same issue. It seems like something is getting hot and causing power to be shut off to the ignition and keeping power from getting to the ignition/dash until it cools off. I hate these kind of issues because it is so hard to track down.
Pretty much like clockwork. Every 9 seconds the power dies for about 1 second and then comes back on. Sometimes the Theft light comes on.
If I am at idle, the car dies. No check engine light. The car has had all new ignition parts in the last year except battery and alternator.
For years, intermittently, my Check Engine Light was on steady. The Ford dealer tried four times (at a cost to me of nearly $400) but was never able to fix the problem. I was always able to get it smogged because I took it in during those periods when the light was functioning normally. But now I've got to get the car smogged again and the light is dead. Could be the bulb or something else. Should I take it to an electric shop or a regular mechanic? I understand that CEL issues are common to Fords of this vintage, but the Ford dealers haven't been useful.
View 15 RepliesI have a 2000 Grand Marquis. Yesterday I turned the key and the starter didn't crank. Everything else came on like it is supposed to. Radio, dash, warning lights, etc. After trying a few times, it started but the starter wouldn't disengage. I had to disconnect the battery for it to stop. I changed the ignition switch and cycled the key, but when I try to hook the battery back up, the starter immediately begins to crank. Even when the key is off and out of the ignition.
