On your Mountaineer the abs and awd wiring harness is tied together in three segements. just removing the fuse will not solve the problem. one of the 3 segements of the wiring harness is bad. usually it is the rear most segement of the harness. that connects to the abs sensor. you can test each segement for electrial continunity with a multi meter, to see which segement is bad. it is a dealer item so you will have to buy a new portion from the dealer. once you determine which of the segements is bad.

Sounds like a wheel bearing or possible loose brake pads or even both lift the vehicle and see if you can either way from side to side as well as up or down move the tire ( look for excessive play if not then remove the tire and inspect the brake itself is the wear bar touching the rotor ...but maby as well a ball joint .however it sounds from your description to be a wheel bearing

You should visually inspect the wheel sensors, You need to have the ABS scanned... also, a collapsed brake hose can appear to be fine externally, you need to remove it to see if fluid flows throught it and back... the clicking can be a worn outer CV joint, make sure the boot is in tact, and hasn't expelled grease, the can also set your ABS since the LH sensor or reluctor (pick up ring) could be contaminated with grease ans road debris.

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).

The advance trac and awd are not working correctly At start up my 2005 mercury mountaineer has the abs light on , after driving about 50 yards the awd lock light blinks several times then goes to awd...


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

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.

Interior light stays on when doors have been locked and doesn't go off. Also when travelling at 10-15ks and you have your foot lightly on the brake peddle you can sometimes feel the abs kick in, Now and...


For the problem with your lights, Have you checked your dome light switch to see of maybe it didnt get switched on somehow? And your brake problem could be that you are low on fluid and the feeling that your experiencing in the pedal could be because you are riding the brakes. It is very very bad for you to even rest your foot on the brake pedal while driving and not directly needing to use the brakes. That can lead to deadly results. I suggest that you start with checking the fluid. If its low or any other color besides clear, I suggest you have your brake system flushed.

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.

My abs lights on and my brakes hit the floor. then heater dies


check your anti lock brake system and your buster

Anti lock brakes light


Good Day,

Usually that indicates bad ABS sensor or ABS component in the system. The quick fix is to locate the ABS fuse in your fuse panel, remove this fuse and abs is disabled. Your brake will function normal and it is safe to drive w/o abs until you can have it checked out, keep in mind you will lock you brakes under heavy braking conditions.

hope this helps
