Does it shift to 4wd high range ? If so then shift to 2wd . What is going on here is the transfer case motor is stopping due to the motor position sensor has gone bad which means that you replace the transfer case motor assembly. But if you wish to make it a 2wd for awhile then remove motor and manually turn shaft . This can be done by raising and supporting rear axle truck in park remove motor turn shaft slowly with pliers and rotating the play in drive shaft. There are stamped markings on back of case showing gear positions..
ON LEVEL GROUND
With the transmission selector in "park", start the motor.
With your foot on the brake pedal (steady-constant pressure), move the transmission selector gear to neutral- then turn the 4 X 4 selector knob to 4-wheel drive high. Wait for the 4 X 4 engagement.
Once it is in 4-wheel drive high, with the transmission selector still in neutral, quickly pump the brake peddle twice, keeping you foot on the brake pedal on the second pump, turn the 4 X 4 selector knob from high range to low range. The transfer case should then change from 4-wheel drive high to low.
Electronics being what they are, you sometimes have to repeat the process. You may even have to inch forward or backward.
[I have an '01 Excursion and an '05 F250 with 4 X 4 on the fly...I miss my '97 F250 with the manual 4 X 4 shift on-the-floor!]
Anyway, check the fuse panel for any blown fuses.
Double check to make sure that the problem is not just blown 4 X 4 lights on the instrument cluster. With the nob turned to 4-wheel drive, have a second person- a spotter, check to see if the drive shaft to the transfer case is moving. If it isn't, you have to delve into the troubleshooting process.
Check the solenoids, vacuum hoses, vacuum actuator, and transmission range sensor on the transfer case. .
With the engine running, put your foot on the brake and shift the transmission to neutral. Now move the transfer case shifter forward till it stops then push it down towards the floor and forward again. You should now be in low range
Hello Joey... Have you ever put your Rover into Low range? You might have accidentally bumped the shifter to the right and it started to select Low range, but it is in Neutral because the Low shift was interrupted. To correct this, with the engine off, but with the key on, select Neutral first. Then start selecting Low by putting pressure on the shifter towards the right(to engage low, the second set of gear/numbers). Keep pressure on the shifter until the dash shows a Low range light and is no longer beeping...now you are in Low Range. Next try to select High range by putting slight leftward pressure on the shifter. Keep pressure on it toward the left until it quits beeping and no longer has any gearbox, neutral, or low range lights (20-30 secs Max each way/Range, etc.) Then select park and try restarting the engine, if you hear any funky/grinding sounds shut it down and repeat above process. It should work on the first try, however, You may Try it a few times before giving up on it if you never use low range. The Low range shift solenoid is probably shot if you cannot get it back into High Range, etc. Good Luck, Brian
Turn the electronic transfer
case from "2WD" to "4WD Lock" to engage the high range 4WD, if the dodge
truck is equipped with an electronic transfer case; otherwise, shift
the transfer case lever from "2H" to "4H." The electronic transfer case
is located on the instrument panel and is marked with "2WD," "4WD Lock"
and 4WD Low." The lever-equipped transfer case is located to the right
of your leg and is marked with "2H," "4H" and "4L."
Shift the transmission into
"Neutral" while the vehicle is either stopped or rolling at 2 to 3 mph
to begin engaging in the low range 4WD. Turn the electronic transfer
case to "4WD Low," if the Dodge truck is equipped with an electronic
transfer case; otherwise, shift the transfer case lever from "2H" or
"4H" to "4L."
Tips & Warnings
Indicator lights will come on and alert you that your vehicle is in either the high or low range of 4WD.
Do not engage in the low range of 4WD drive if the transmission is in gear; you must shift to "Neutral" first.
trucks allow you to shift from 2-wheel drive to the high range of 4WD
at up to 55 mph--consult your truck's manual to ensure that this is
possible. Do not exceed 55 mph while engaged in the high range of 4WD.
Do not exceed 25 mph while engaged in the low range of 4WD.
Do not engage in 4WD unless you are on slipper or rocky roads.
This is very strange because of How the low range is engaged. I drive a 1999 F150 4x4 which has the same dash and controls for the 4x4 as your Expedition. I do know that the fan control switch is unfortunately the same shape and very close to the 4x4 switch. It is easy to grab the wrong knob and turn the wrong thing than was intended.
My initial impression is if it is possible, your girl could have reached over to move the fan switch and actual grabbed the 4x4 switch instead. Or you were warming up the Expedition and meant to turn up the fan and instead turned the 4x4 switch to Low. Or a backpack she was moving with schoolbooks could have hit the switch. What puzzles me is that to go into Low range, you need a foot on the Brake and simultaneously need the gearshift in Neutral and the 4x4 selector in Low. That is 3 things to make the low range happen.
Even if your foot was on the Brake and the sensors caught the gearshift going through Neutral on its travel to Park, the 4x4 Selector would have to be in Low. There is one problem you can have with the 4x4 Selector.***The Selector has 3 Resistors and a LED bulb.***
You stated the Selector switch was good. This would mean there were 3 different Voltages under the vehicle. Sometimes when the LED bulb burns out, it shifts the Voltage out of range for the Servo, and although the Selector says one thing, the Voltage at the Servo has the wrong value for that function. Since the dash light and the Servo agree on Low, it would seem the Selector is out of sync with the other 2 parts.
I hope my solution is very helpful in solving your problem.
low range means you are in 'low range 4 wheel drive' push the button while the engines running and the gear shift levers in neutral to switch to high range [or 2x4] low range,cannot drive over 15 miles per hour,high range can drive up to 65 miles per hour. see the difference? you need to shift the transmission to neutral,while the engines running,and your foot on the brake pedal, push the button on the 4x4 to light up to the two wheel or rear wheel diagram. then when it lights up the 2 rear wheels, it's in rear wheel drive. if this does'nt describe your problem! please do not attempt anything and call toll free# for mercedes roadside assistance for free at 1-877-815-9962 these people have been a great asset to my buisness. thank you for choosing fixya.com
