Someone has got to know something on this issue, am I the only z71 4x4? :think::think::think:
It's a problem with the buttons thenIm going to restart the computer tonight and see what that does. The 4wd wont even work while that dam light is on, this shit sux dude. issed: I will let ya know if this works out.....W/F
It's a problem with the buttons then
Mine doesn't work when I get the code.
Sometimes the unit will say I'm in 4lo when I'm in 2hi :rofljest:
Damn thanks for the info man, Sounds like you know a lot about these trucks. Will do tomorrow for sure if the restart doesn’t work. :shake:the buttons usually mess up
it is easy to take out and resolder all the points on the board. U can usually see which ones are cracked.
If the switch seems ok try the ground wire below the drivers door by the body mount. I read that this causes loads of troubles with the 4wd system too. After these 2 checks then id look toward the encoder on the transfer case.
process of illimination will find the culprit.
kenny had a similar problem. It turned out to be the electric module on the front diff. The piece where the electrical connector connects. Take a crecent wrench and unscrew it. Once its out, check to see if the pin is in. If its all the way out then that module is messed up. if thats the case swap in a new one and it should be good to go.
Damn I never heard of this site!!! Thanks for the heads up bro.... :cheers:Mine has about 98,000 miles. The 4wd switch light goes dim and sometimes just doesnt light up. Yeah, I think it's just the selector going out. I heard thats a common problem. Gm parts direct has them for around 40-50 bucks.
Put fluid in the diff. then before I went to bed disconnected the battery cable from battery. When I cranked it up in the morning before work it did run a lil rough but only for a few. That’s just the system is re-learning itself!!!! What going on with yours?How did you restart the computer? Did you just add fluid in the front diff or both?
