Question about Mercury Mountaineer

2006 Mountaineer 4x4 light on awd stuck.

2006 Mountaineer AWD. 4x4 light is on and 4x4 is engaged all the time. All new tires. Transfer case fluid changed with no resolution. Disconnected wiring to transfer case and it doesn't seem to be locked into AWD anymore. 4x4 light off but "wrench" light is on. Transfer case issue or transfer case motor issue? Thoughts?

Have a shop diagnose the problem if you
have not purchased the factory diagnostic
manuals from Helm.Com
Don't know why you would think fluid change on
any part of the vehicle would do a thing
Have you not checked for codes
That is always the first thing you do even
without a MIL lamp on.

    Shop said to put new tires on and flush and change fluid in transfer case. No codes showing.

  • Anonymous Jul 24, 2013

    All your saying is the shop you went to did not diagnose a thing Just sold you tire & changed the fluid Start over at a shop that understands why your there This is an epidemic with all vehicle issues apparently,we get close to a 1000 people a week that can't get anything even figured out to get to the point of making a repair

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

the brown wire is for the electromagnet inside the transfer case to engage the clutch if the wire is broken right at the case the magnet will need to be replaced

SOURCE: My 2003 Mercury Mountaineer V8 AWD transfer case

the problem is the chain inside strechs, could cause case damage, it will soon break and then truck wont move, depending on how bad it is you may be able to drive a bit more, threres just alot of strain there because of it being awd, if it is noisey it doesnt have to be replaced just fixed,good luck.

Testimonial: " Thanks! It does make noise, a clunking sound when I back up and cut the wheel to the left or right. The tires skip also. "

if not AWDhttp://www.fixkick.com/tranny/xfr-case/4wd%20windup/suzuki-grand-vitara-4mode-4wd-selector-switch.jpg

4L is never for dry ice free pavement, ever.
on both AWD and PT 4wd
never
the operators guide says that and the damage word.
read it , lost it? we have it.ask...?

KNOB, see the word lock, ,

http://www.fixkick.com/part-time-test.html

no center differential in 2L lock, at all.

the rule in 2L is this.
one tire needs be on ice, or dirt.

same with PT box.

true for VIT and jeeps. lock or part time 4wd

I have a 2004 GMC Envoy XL and the high range 4x4 mode will not engage. The AWD system works just fine as well as the 4x4 mode in low gear. What is causing this?


Is the Service 4WD light coming on? Do the light on the 4x4 selector switch indicate the proper selection and are on steady after a few seconds? If there is no Service 4WD light on and the selector switch light are correct, the only place for the problem to be is the Transfer Case. Has the Transfer Case fluid been changed at 50K mile intervals? This is very important.

Wil putting two size tires on a isuzuvehicross make the transferre case go out.


Yes...
The tire sizes are important on any 4X4 vehicle... IF you engage the 4X4 ... or is you have an AWD vehicle...

If the tires are different sizes , front and rear... then the front and rear axles will turn at different speeds... not in sync with the gearing of the transfer case.

Unless this vehicle is being driven on snow , ice or mud.... while in 4x4 mode... this is very bad.... for axles and transfer case...

Bad grinding noise that actually binds up the vehicle so it won't go. Sound like brakes but have already replaced brakes, wheel bearings, front axle arms, new tires, and checked the gear, the awd light,...


The problem is likely the transfer case has locked up, the question is do you need it to continue to be an AWD vehicle? If not a simple solution is to remove the driveshaft from the transfer case to the front differential case. Takes maybe 15-20 minutes and there are no leakage issues by doing so. The vehicle will now be a rear-wheel only drive one. I recently did this to our own 2003 model and as the car stays in the south, there is no need for the AWD. The car performs as expected and that binding problem is gone.

I have a 2000 bravada and the awd doesn't isn't working. I took to the shop I usually get work done at and they said it was working fine. I am no mechanic but when the front tires aren't moving and you are...


I'm pretty sure the computer controlled NP-136 transfer case (which uses two speed sensors to sense the difference in speed between the front output shaft and the rear output shaft, and engages the front axle accordingly) was installed in 1998 and later models.

These trucks (mine included) use an "Active On Demand" transfer case. Basically its a normal 4x4 transfer case with a big electrically actuated (by way of a motor) clutch that connects the front prop-shaft (which is being spun by the wheels full time) to the transfer case front output. Its all in the transfer case.

Good luck and hope this help, check all the fuses and the wire harness to the encoder motor and replace the encoder motor if it has gone bad. Try bring it to a transmission shop that is familiar with the AWD system on your Bravada. The earlier years were a different system, 1998 was when the change was made. 1997 and earlier use the Borg-Warner 4472, which is always engaged with the use of the viscous coupling. Both were marketed as "SmartTrak" though.

Sounds to me like the transfer case actuator motor is either faulty or it is being told to be on all the time (which it shouldn't be).

1999 olds bravada smart trac four wheel dosent engage


Probably the transfer case encoder motor. Unplugging it at the wiring harness should make the "service awd or smart trac" light come on. This will tell you the awd controller module is probably OK. Common failure item to Bravada's. Try "thepartsladi" eBay store for lowest price motor, beware aftermarket!!! Also make sure transfer case fluid is "blue" GM Auto-Trak II only! If not bllue when checking change twice after driving for a week with blue fluid.
