I'm pretty sure the truck has to be at a complete stop with the transmission in neutral before it will accept your low range input selection. Unlike 4wd high.

89 bronco ii won't go into 4x4 or low range


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. .

03 yukon not staying engaged in selected range push button


possible 4wd selector switch problem. 1st try unhooking battery for 10 min, then rehook and start engine, attempt shifting into 4wd and see if it clears up. could be multiple different things causing this, as the 4wd system is computer controlled, and electronically engaged.

How do I turn 4wd on?


    • 1 Start your Dodge truck's engine.
    • 2 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."
    • 3 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.
    • Many Dodge 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.

I own a 1999 Expedition that I used the 4wd High on 2 dayss ago and never used the 4wd Low at all. As I got home a put it back into AWD and parked it. Two mornings later I climbed into it to take my...


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.

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.

The transfer case is stuck in the low range. If manual shift try shifting from low to high several times to see if free up. If electronic, check all fuses and make sure you hear transfer case change range. Do this by shifting with key on engine off. If no change refer to qualified transmission mechanic.
