How do you turn off the FWD of a 1998 Mercury Mountaineer?

If your vehicle is All wheel drive you don't unless you drop the front drive shaft, but don't my 1999 is AWD it has saved me numerous times.

Why would clutches in all wheel drive 2000 Merc Mountaineer make noise and vibrate slip when starting out in a turn once vehicle has warmed up after fluid changed in transfer cases and rear?

If the vehicle has a limited slip type rear differential, friction modifer needs to be added to the rear differential fluid. If not, the clutches will bind and growl at low speed turns. After you add the friction modifier, it is best to do several figure "8's" to circulate the fluid. The groaning, and growling should go away within 200 miles, if not the clutches may be worn out. ( The additive is available from your dealer)

Where is the passenger side oxygen sensor?

I have a 1997 mountaineer. There are 2 sensors on the passenger side and 2 more on the right. Crawl under your rig on the passenger side and you will see them mounted on the exhaust pipe near the catalytic converter. The exhaust on my truck has two exhaust pipes leading from the engine and they are both set up pretty much the same. locate both sensors (they are mounted on the top of the pipe) and change the one that is indicated as failing on the OBD II read. Bank one is the one closest to the engine and bank 2 is the one farther from the engine. Remember to disconnect the wire first when disconnecting and when you install, put the sensor into the pipe and then connect the wire to the harness as the final step. There is a special socket available to help with this job but I used a box wrench and it went pretty well. Hope this helps. Its the ONLY thing that comes off of the exhaust pipes with electrical wires attached. (EX. Bank 1 sensor 1 default would be the drivers side BEFORE the catalytic conv. Sensor 2 is after catalytic con. Bank 2 is passenger side -- just in case you need that info) Good luck and use lots of PB blaster

What size speakers will fit in your 1997 Mercury Mountaineer?

I had a pair of Bang and Olson's which measure 36"x17.5"x15".. They were still in their box and they fit right in next to my bowling bag which is a 4 ball roller. Was no problem getting them in or out.... I would suppose you could fit in a bigger pair. I had an executive deski, about 60"x32"x30" and it fit in as well... I had to fold the seats down but was still able to close the hatch.

What does it mean when the Fuel reset light came on mountaineer mercury 1997?

On a 1997 Mercury Mountaineer :

That means that the fuel pump shut off switch ( inertia switch ) has been

" tripped "

It is a safety device that does not allow power to the electric fuel pump if

the vehicle has been in a collision ( or maybe hitting a bad pothole )

The switch is located in the front passenger footwell , by ( or behind ) the

kick panel

If you don't smell gas or see any gas leaking , push the reset button down that has popped up on the top of the switch

Turn your ignition key to the RUN position for a few seconds and then turn your ignition key to the OFF position

Make another check for the smell of gas or any gas leaking , if none , go ahead and start the engine

Your 1999 Mercury Mountaineer headlights keep randomly shutting on and off you have checked fuses what could be the cause?

Ok it was the "turn signal" or "multi-switch" the switch that controls wipers,turn signal,brights and dims ect. it was pretty easy to replace and was about $60.00.

AnswerDoes it have automatic headlights? If so, it may be the sensor. It could also be a circuit breaker. Many headlight circuits do not use a fuse, instead they use a circuit breaker so that you won't get stranded without headlights.

If it's a circuit breaker problem, you may have lights that are drawing too much current for the breaker, on the other hand, it could also be a faulty breaker... assuming that you have a circuit breaker in that vehicle. You may need to do a little research, either at your local library or at the dealership. Sometimes a dealer mechanic will give you a little information so that you can perform some of the more simple repairs yourself.

How do you replace a blend door motor on a 2002 mountaineer?

2002 was a changeover year for the HVAC system by Ford so the answer is different dependent on whether you have the older or newer system. The same systems were used on Explorer, Mountaineer, Mazda, and other vehicles. On both systems, the problem is usually not the motor, but the blend door itself. The door breaks on either system(for different reasons) and the computer system detects a fault and shuts down the actuator motor. Generally a "dead motor" is just the computer shutting it down, not an actual failure of the motor.

You can check the location and functionality of your actuator motor by identifying which system you have from the pictures and following the procedure on how to check motor operation with a 9V battery and a snap connector. The diagnostic information and suggested fixes are available on heatertreater.net.

Where do you find the keypad code for a 2004 Mercury Mountaineer?

Do you need to replace the EGR on your 2000 Mercurn Mountaineer 5.0 if you are getting a p0401 egr flow efficient code?

Possibly, but not necessarily. IT may be a dpfi valve that is plugged, a piece of carbon caught in the EGR valve, carbon build up elsehere preventing circulation. Take it to a independent garage that specializes in troubleshooting of this nature.

Answeri was getting a p0401 and a p0402. Follow the steps for cleaning below:The EGR on the 97 merc is on the back left side on the intake near the firewall. I have had sucess with cleaning out the throttle body and pathway to the erg for clearing the MIL or check engine light for odb codes related to excessive and inexcessive flow rates in the egr. Open the hood and locate the air box for the air filter. Connected to this is a large semi flex tube with a clamp at each end. One at the air box and one at the throttle body. Just remove the clamps and push open the butterfly valve and spray out the insides with carb cleaner. Note, if you have low miles, under 100k, I would not recommend this, because they seal them with a coating and you may cause further problems. However, if you are like me you will have over 100k. I have 127k on mine. Don't start the vehicle right after this. Spray it out several times and and let if dry out. You can prop a screwdriver in the spring just to the right of the TB valve. It is tight to try to remove the egr in your driveway. One of the two screws is ok to remove and the other is very difficult with standard tools. If you wish to see what the egr looks like check out autozone or parts America web sites and search for egr and I know at least one of them has a picture of one.
