Hi everyone, heres my problem, my 2002 envoy is always 2wd not matter what the switch says. the light on the switch blinks for a long time and then goes into position, but its not actually 4auto, or 4hi. As soon as i turn the switch to 4lo the light blinks and then goes out, and the Servive 4wd light comes on? also the t/c wont go into Neutral. the red N only illumnates for a sec when you turn the key. then goes out, nothing happens when i turn the switch over to N. i can hear the front actuator when i turn the switch. and i hear the encoder motor but i sounds like i binds and retries. ive tried the #8 fuse thing, nothing-same stuff. :confused: thanks

Sure sounds like the encoder motor. Or internal binding in the transfer case - a lot more expensive to fix that. Good luck!
