You current issue is no different than any other
vehicle problem you have had since 1996 when
the OBD2 Systems came into being

You have a MIL Lamp on or check light as some people
call it

You should have checked fore codes immediately within a day
or so to at least know the codes & then googled them to get
some idea of the issues

You know that you have an ABS Braking System issue based on
your owners manual & your abiltiy to recognize Advance Trac etc

Have to have a shop diagnose that system with professional tools

With an AWD issue possible I wouldn't even use it until fixed

The trac control is ussually a bad wheel speed sensor or related
issue

SOURCE: My Advtrack, ABS and AWD all get Disableed

The sound could be isolated and may not be related to you not having 4wheel drive. You may have to inspect the speed sensors on the hubs of the wheels. You may have it inpsected and see if there could be a faulty sensor. Some 4x4 relies on sensors for 4x4 to work and these sensors also help ABS to work. Inspect the drive shafts as well. This may have caused the noise and may have affected your 4wheel drive capabilities.

If the vehicle is made to be a AWD you cannot get it out of AWD unless you take off the front drive shaft

SOURCE: I own a 2004 Mercury Mountaineer, and the ABS

On a Car like that you have little sensors on each one of the wheels. These sensors are small, delicate and finicky. You probably have a loose one or when the wheel heats up or reaches a certain speed, highway driving, it loses the connection and the light comes on.
The best way to fix this is go to a shop. Since the answer lies in the computer somewhere they need to check it. Note that the computer on your car stores the data when this happens and they should download the stored data if everything " seems fine ". Hope that helps

SOURCE: My ABS light is on and its like the brakes are

Bring the vehicle into a repair shop ASAP. There are several things that can be wrong such as calipers master cylinder, module,fluid exhaust valves . ABS problems will affect AWD. So in all likelyhood once ABS problem is cleared AWD will be fine.

How do i get the advancetrac light to go off, is their a sensor or is it in the transfer case


Christina, May just be a loose Tone ring, plug/wire,wheel speed sensor, etc. You will have to take vehicle into a good shop and have scanned for diagnostic codes to determine which sensor,wire,etc is bad and causing the advance track light to display and estimate repair. Check the attached links,instruction and guides, Good luck

I have a 2005 mercury mountaineer and the abs light and the awd light is on and it feels like the tires and locking up can anybody tell me what going on


It means you are driving in All Wheel Drive mode (not recommended for driving on regular roads, so turn it OFF), and that the Anti-lock Brake System module has likely failed (possibly because you were driving around on regular roads with All Wheel Drive turned on).

What are the signs off front wheel bearing going?Would ABS and AWD lock come on?


Generally not, you will hear a low rumbling vibrational sound when you are driving. Sometimes when you accelerate your wheel will feel like it is moving up and down.
If your ABS and AWD lock lights come on, you need to get your vehicle looked at and diagnosed.

My 2005 mountaineer Advtrac, ABS AWD and O/D Off flashes when im driving and no one can tell me what is wrong with it.


People can't tell you what is wrong with any vehicle issues

You must understand the technology and start a diagnostic
proceedure to find those problems

You have an ABS System issue
You retrieve whatever codes there may be & go from there

Obviously a repair shop or dealer can resolve it

I am having an issue with my 2004 Mercury Mountaineer. The AWD is giving my some hassle. It seems like most of the time it is not working, but every once in awhile it does work. Not sure if it is the...


Is the check engine light on? Most of the time it should be off to give the best gas mileage and if all the tires are the same you might not even be able to tell going straight down the road. Do you rember it working more pronounced before or is this a new vehical to you? If it's an electrical problem the ABS or trac light will come on and or the check engine light. If any of these are on the vehical needs to be connected to a scannner that has a regular operator and have them check for problems. You can check that the air in the tires are the same and that the tires are the same and about evenly worn. If the brakes need to be serviced, ( out of adjustment or hung up) The ABS system helps the AWD do it's thing and all systems need to work correctly for the AWD system to work correctly. If all your inspections don't come up with something to be corrected, And you do all the adjustments that you can and the system still is'nt working to suit you, a scanner operator needs to connect to your car and check it further. ( Not a code reader )
