1996 silverado z71 4x4 questions

[Snyder729]

Okay so i purchased a 1996 chevrolet silverado z71 fully loaded, lifted 6 inches with 36" tires. When i first got the truck when i tried to put in 4wd it would do nothing. But today i had my dad check it out with me and now to use 4wd i have to put it in 4lo then to 4hi if i wsant hi and if im in hi and want to goto 2wd i have to put it in 4lo to pop it back to 2wd. Does anyone have any idea why it does this? And why it would just decide it wanted to start working??

I presume you have the pushbutton switch for your transfer case. What does it do when you push the 4Hi button when you are in 2Hi?

Sounds like the encoding motor is gone to me.

Can't say that I've heard of that problem. You might waqnt to call the dealer and ask them if no one else here can help you.
Good luck.

When i click 4hi when im in 2hi it does nothing but i can go from 2hi to 4lo then to 4hi.

I worked at the dealership here for 2 years and the ****ers want over $100 to diagnose the problem and if it is the coder they want 800 for it. I figured out that my push switch had a bad connection inside it or sumthing so im getting a new one tomorrow. And i guess ill have to live with the fact i cant go from 2hi to 4hi and just do it the ghetto way.

Okay so i got the new interior switch. The old one was bad but now it will clank sound when i switch it into 4 lo or 4 hi but the front wheels dont spin at all. What could be my problem?

Sounds like it could be the actuator to me. When I had my lift put on they forgot to plug mine back in sounded similar to what you describe.

[Snyder729]

So u think my actuator might not be plugged in or it may not be screwed back in?

Or the actuator is bad???

[Snyder729]

is their any way to test and see if its bad before i buy a new one?

And what is the possibility of it being my coder or whatever it is?

[Chevyboy96]

Maybe unscrew it and see if it works?

Did the 4x4 ever work when the switch was bad?

[Snyder729]

When i purchased the truck the switch did not work so i had no clue if the 4wd did or not. the guy i bought it from said he didnt know if it worked or not.

[Snyder729]

any idea on how to tell if the actuator works? What should i look for when i pull it out?

Pull it out and see if the actuator moves when you put it in 4X

[Snyder729]

okay so i pulled it out and had my dad look at it when i popped it into 4wd and the actuator didnt move. So i am guessing that must mean the actuator is bad? or could something else be stopping the actuator from moving?

[Snyder729]

anyone???.

[Snyder729]

Okay so i bought a new one plugged it in and it now moves, im hopeing the problem is solved, but i guess i wont know till i hit the mud =D

[Chevyboy96]

what kind of ass buys a 4wd truck and puts a lift and big ol tires on it then never uses the 4wd.
