Was working an then it just stop coming on it told me I need wiper fluid an shut off an didn't illuminate anymore checked for fuses all were good

My engine light on my 2007 Mercury Mountaineer came on so I did a diagnosis and it said it was my spark plugs but I just had my spark plugs done they're brand-new

What's caused my headlight to blow?

sometimes it will fix itself for a little while but goes right back to doing it. I have been manuelly shutting off the inside light and the headlights so if the alarm does go off it will not drain my battery.

change fuel pump relay safety swich still in down position disconnected in line to fuel filter turned on key no gas

How do I change the cabin filter ?

Was able to get them to work when I hot wired or bypassed the driver door switches.

It rattling all the time.

my mercury keep loosing coolant, my mechanic changed the thermostat head. and still having the same issue.

When I put it into reverse, sometimes, a little wrench light comes on and a message that says, "Check transmission, engine in failsafe mode" comes up. But when I turn off and restart it is fine. Sometimes when I put in reverse it feels like it doesn't want to go.

All the bolts have been removed but we can not remove the evaporator. Is there a trick in removing the evaporator?

the 01 mountaineer has 80,000 miles..driving slow through a lot we hear a thudding/grabbing sound low pitch. we notice this when leaving from a stop or when making a slow turn in a lot. the sound is intermittent. the vehicle is an AWD. two shops couldn't figure out. one a Brakes plus only changed the middle transaxle fluid .. no luck on that.. the car looks like new outside/runs good at speed. too nice to dump but cant figure it out. Thanks

I can turn the light off when the vehicle is in drive, but not when it's in reverse, & the sensors aren't working so it is off as it's showing, but I can't turn it back on, was working fine before having my Transmission replaced/rebuilt, sensors are clean, no damage, haven't hit anything, just won't let me turn the sensors from off to on while in reverse, like it should, usually when switching to reverse the light is off &stays off &the sensors work, &I could turn it off if need be but I never have, except when 1st trying it out, 102,000mi on vehicle, only have had it for 1&1/2years, &bought it with 92k mi on it, it's still under warranty from the dealership, at least for major parts like my transmission, 3y 36k mi warranty, no other lights are on, not having any other issues with anything, never had a vehicle with RSS or anything similar before so my knowledge on vehicles is a bit old fashion, this just started to do this today, haven't left my driveway, verified the sensors are indeed off & not detecting major obstacles, like our other vehicle we tried parking behind me, so it's not just that the light is on &showing the sensors are off while the sensors are still on, &the only issue that is mentioned in the owners manual in regard to the RSS system is about the light being on reading off &the sensors still on &detecting obstacles, instrument panel does not show any issues, codes, system check is fine, tho it doesnt check the sensors, any help is greatly appreciated

Died while driving down the road tried to start again tries to but will not start

replaced thermostat and flushed cooling system. still having problem.
Does radiator fan have a clutch?
Or any other ideas

The car shut itself off without any warning on an intersection after continuous high revving with a stuck gear. Struggled to start but when it did a loud squealing sound occurred and shut off again. I pressed the fuel reset switch and it started but the engine ran different and would not move at all. After a week a loud knocking/rattling sound occurred after starting and still won't accelerate. (It also did have a transmission problem with gear 2) Could it be that, time chain cassette, worn engine or what?

I purchased 8 spark plugs and need to know how to install them

I purchased a fuel filter. How do I install it myself?

even when the doors are shut the light remains on.

Tried turning off with key but all it does is act like it works but doesn't turn vehicle off what u think is wrong?

it starts up fine shifts when driving but its hard to get to take off when you start because it dies. it just started it today

don't know any other info.

Twice now I was driving down the road when my headlights and dashboard lights would shut off without any warning. In a panic I'd be trying everything I could think of to get them back on. Both times I reached up and somehow the headlight switch was turned completely off. I've asked several people about it and they all laugh at me and say im crazy. And the last time it happened i passed a cop right as my lights came back on. I'm desperate for an answer. It's like someone or something reached up and turned it off. And there is absolutely no way I could have bumped or touched it at all.

While driving lost vacuum or something because it would just crawl when accelerating on small grades.

Has full charge on battery, sounds like it wants to turn over. Just grinds and won't start.

I have a good battery, and alternator, starter. It cranks but won't start. I've shut off all my lights dome lights ect. I've pulled the power window fuse as well. I was told it was my power windows by a mechanic.

When my 2002 Mercury Mountaineer is on, there is a constant noise of what sounds to me like gears grinding. Its coming from the latch on the rear door. It never stops! I am also having issues with the alarm coming on at random times, mostly in the middle of the night, could these be related issues?

I turned it off and then realized I needed tk go to gaa station and when I turned key. Nothing, no lights or anything. Evwn the cd in cd player ejected. Please help

the rear lights do not turn off
even if i turn the car off and no key in the egnition
