1999 GMC Suburban V8 Four Wheel Drive Automatic 155000 miles
My transfer case suddenly will not go into neutral, 4 hi or 4 lo. When the button on the dash is pressed, the front axle actuator motor hums and engages, but the actuator motors runs and appears to "hunt" for a few seconds, then stops, leaving the transfer case in 2 wheel drive. From all the research I have done, this sounds like it is probably the encoder motor sensor, and not the motor itself. (I don't have any way to check for the "CO327 code to confirm this theory.)
Is there anything else you would recommend I check before ordering and replacing the sensor?
have the same problem?
