Hi guys,
Today I had to get a tug from another vehicle in order for my avy to tow my boat out of the water.
Vehicle in question: 2002 Avy z71.
Symptom: Truck will only operate in 2wd no matter what. Cannot get front wheels to engage.
Here's what I've checked.
1) Pushbutton switch on dash: can select auto 4wd, 2wd, 4x4hi. Button will not select 4x4 Lo.
2) Fuses: 4x4 fuse (driver's side of dash) is good. ATC fuse (under hood panel) is also good.
3) Removed front diff actuator: Tested ok - visually protruded and retracted when pressing button.
4) no "service 4wd" alert on dash
Can someone point me what to check next? Maybe the transfer case encoder motor?
The truck is new to me.... I hear that some people have issues if they don't change their transfer case fluid at recommended intervals?
