I have a 2004 Envoy 4x4 in line 6cyl that wouldn't go into 4x4 when I first got it. Finally it went into 4lo but now it will not come out. I have tried it in neutral rolling/stopped both as the manual says. Tried rolling down the street backwards (in neutral). Even tried with front wheels off the ground. No luck.
Transfer case fluid was just changed at 114,000 miles. (not sure of it's history before now. Just purchased the truck). Auto track 2 fluid was used.
I can hear the 2 distinct buzz sounds of the TC encoder motor
I think I remember hearing the front actuator as well before it finally did go into 4lo. Now that it's in 4lo will I not hear it? Remember reading that the front actuator only turns on when switching from 2 wheel to all wheel drive. Is this correct? If this was bad would it keep it stuck in 4 lo?
I have all the proper lights on my knob. When switching from 4lo to any other option, the new option will blink steady for about 5 seconds but then default back to 4lo.
The service 4x4 dash light is NOT lit.
When spinning one front tire the other tire turns the opposite way - but there does seem to be a couple of inches of play before it will engage. Is this normal or is something worn out?
What should I check or replace first? My hunch is the transfer case encoder motor. Would like to narrow it down with more than a hunch.
Thanks for all you help in advance.
