Hi,Welcome to Just Answer I am sorry to hear you are having problems with your vehicle I will try to assist you in any way I can to get you going again. If you were instancing a new Transfer Case Encoder Motor the new motor is usually in neutral and you have to put the transfer Case in neutral. Try Putting a wrench or channel lock pliers on the splines and turning it until you get it in neutral. You will Know it is in neutral because you will be able to turn the driveshafts while the Transmission is in park. Than you should be able to install the encoder motor.
Yes, Once the system is working again with no faults the light should go out.
Sorry I made a mistake here is the correct Info :
Important: Before the motor/encoder is removed, ensure that the motor/encoder is in the 2HI position.
Your phone # XXXXX not show Up in your reply.
You have to disassamble the motor. I will send you the info.
What is your VIN#?
Do you Know what transfer case you have?
Important: Gently lift the rotary position sensor and wiring to disconnect it. The internal wires go to a connector within the motor housing. This internal wire connector does not have a locking tab and is easily disturbed.
Important: Look at the motor/encoder housing where the rotary position sensor was removed from. Take note of the "Hex" in the housing where the new sensor will seat when properly installed.
Important: Provided the rotary position sensor was removed, follow steps to install the sensor, otherwise proceed to installing the motor/encoder to the transfer case.
If there are brushes inside the motor it may be difficult to put it back together properly. So unless you can put it back together you will need a new motor.
Properly align the keyway of the rotary position sensor with the motor/encoder shaft as indicated by the center reference line shown in the picture.
Will it go into 4w Lo when you try, you need to put the transmission in neutral while the truck is running. What do the lights on the switch when you change modes?
