Ok to start off with the system was working fine last night when i went on patrol. But this morning ever since i started running it for the day its been locked in 4wd for the entire day. I can select between A4wd and 4 Hi but i cannot switch it to 2wd or 4lo. I know i am 10K past the interval to change the T case fluid so that is where i will prob start in this process to at least see if the clutches are sticking together causing it to be in 4wd in the T case.
What i know so far:
No service 4x4 light on
No fault codes found on Torque Pro (btw Dmanns i finally spent the $5 and got the pro version lol)
I can select A4wd and 4hi but not 2hi or 4lo
to add a quote from whore thread:
With all the above said off to Google i go! I know i found a couple links when i was looking on the phone earlier...Ironically they were some old Trailvoy links where Roadie had spoken in each. Some of the symptoms are similar but some arent...will add to this post when i find them...
Ok this is a thread on a related issue but roadies answer makes me wonder since it does mention the blinking light on the selector switch im seeing.
Stuck in 4 Low
This thread seems to have some answers here as well once again from our resident Roadie
Awd works but not 4x4???????
Ok after reading the two above links they kinda point me in the right direction or at least closer to where to look. The front wheels do spin when power is applied from a stop so from what i read that pretty much eliminates the front disconnect as well as the front actuator along with front diff and drive shaft as the cause. Pointing more and more towards the encoder motor or at the very least dirty or oxidized sensor in the encoder motor...with that all said how difficult is it to change the encoder motor?

Yeah I thought so.
