The motor shifts into 4ws high with no problem but fails to shift into 4wd. It is a new shift motor. I replace the motor that would not shift in to 4wd high or low.

Thanks,
Jimmy

Sorry corrected question;
The motor shifts into 4wd high with no problem but fails to shift into 4wd low. It is a new shift motor. I replace the motor that would not shift in to 4wd high or low.

Are you getting vacuum to the front axle? I don't know, how do I check for that? Thanks for the reply.

If 4wd high is working, then you have vacuum. Do me a favor. Safely park the vehicle on a flat surface in park and with the brake on. Go under the vehicle and disconnect the wiring harness from the 4wd actuator. Have a helper turn the key to the run position (engine off) and switch to 4wd low. Check to see if you are getting power at the harness.

Thank you the reply again. Yesterday I removed the shift motor leaving the electrical harness connected. The turned the switch to 4wd hi, the shaft in the motor move to the 4wd hi position, the turned to 4wd low and checked the motor again it did not move from that position. Do you want me to check the wiring harness connector for power? Is the a diagram somewhere to show which pins or wires do what?

Thanks so much again for the help.

Thanks,
Checked it out, I get no DTCs on my Actron OBDII scanner. I am no electrician so I and read the schematic. I see the shift motor diagram on the one page and then I see the plug with the pins but I don't know how to check the plug. Thanks for the help.

Basically, you need to check each pin for power when they should receive it. Have a helper turn through the different 4wd modes while you check. Also, make sure you have a good ground.

To check for power, all you need is a test light or a multi-meter.

Thank you, I am going to try and check it out when my so comes over tomorrow. There is also a clicking noise in side the dash when I turn the switch knob into 4wd high, is this normal? I have been reading that it could be the GEM or the shift control module, could this be the problem also? So on the connector for the shift motor all eight pins should get power to them at some point correct?

Thanks Again,
Jimmy

Okay, I am looking at the schematic for your vehicle. It is showing me the following wires:

Vio / Yellow Switch A
White Switch B
Brown / white Switch C
Orange / White Switch D
Yellow / White 4wd output
Brown Electric clutch relay
Yellow Electronic shift solenoid
Orange Electronic shift solenoid

I looked at the GEM wiring and my only concern is a ground from it. It will be a black wire. Make sure it has a good ground. As far as the clicking, it sounds like a relay is reacting to power, so I believe what you are hearing is expected.

Now, the colors I listed above "I BELIEVE" indicate the different positions of the switch. For example, Vio / yellow would most likely be 2wd High, white, 4wd high, Bwn /. White neutral, and orange / white 4wd low. Please remember, I am looking at a schematic and it isn't easy to identify things without the vehicle next to me.

Let me know if this helps.
