Greetings,It was either the T-case switch or the plug at the actuator that got it fixed. I found a diagram for the circuits and would like to post it here, ive read all the forum rules and tried a few things, it's a pdf file thats over the allowed mb's or something like that...let me know if there is anything you can do to help me with it please and thank you.

 

I have a 93, not sure if they are the same, but I believe so. There is a switch on the transfer case and it sounds like it is stuck in the "on" position. I'm no mechanic, but that would be where I would look. Good luck.

 

if the front diff is locking up, then id say its the actuator in the front diff, its probably stuck open, id take it out and check it/replace it

 

Thank you,I think your right
Im getting ready to check that now, i found some info at; http://www.chevytalk.org/fusionbb/sh...d/207294/tp/1/ (The whole page is interesting).
and; http://www.4x4posi-lok.ca/pdfs/troubleshootguide.pdf (look at section#2). Its not the schematic diagram im searching but it sure is some kind of help.

 

Thank you, tested good ,i'm heading towards the T-case 4X4 switch to see if that is the problem. thats the only place i have 'nt checked.

 

i found the schematic on the 97 4wd system but it wont load i wish i could post it somehow. it would help alot of 4x4 owners, mine is fixed and works better than ever.and after a new t-case switch all i can say is never trust that connector that plugs to the actuator,dont forget the old wiggle test(could that have been the cause of all this $$$$$ ?)
