4x4 won't work!!

Nowave2big · #1 10-13-2004, 02:43 PM

I have a 94 s-10 with push button 4x4. Whenever I try to push 4 low or 4 high the button blinks a couple of times and goes right back to 2 high.
If anyone has had this problem or knows how to fix this please let me know. Your help is much needed. Thanks!

Reset your computer by pulling the negative battery cable for 10 minutes and try.

If not, you will need to replace the transfer case vacuum actuator.

Good luck.

if you have access to 4 wheel high you shouldnt have a actautor problem. i dont know if this will help but at a complete stop turn the 4 wheel low button and put the vehicle in reverse and start moving slowly in reverse, then stop. this should put you in 4 wheel low. if it doesnt then check your actautor and wiring. if those are good then its time to look at the transfer case. good luck!

Put it in neutral and then push your button.

Yes, 4LO is usually in neutral.

Resetting the computer will do nothing for a '94. Check your fuses, relay and actuators in that order.

Some people have had this problem solved that way so don't discount it right off the start.

the thing that always worked for me was puting the truck in (N) push the 4L button and as soon as the light starts blinking put the truck in park, that should force it to ingage. It works for me, and it eaven sayd to do that in the owners manual.

It works!! I took the nuetrual off the battery like you guys suggested for 10 minutes and then hooked it back up and it works just like it used to when I bought it. Wow. That saved me alot of time and money. Thanks a million guys!

You are welcome.

It is too bad some people discredit my advice in this thread before trying it.

I am glad my advice helped you.

Ok, I have to ask a question but am gun shy of being accussed of something, but here goes.

I understand that the transfer case signals the ABS what state it is in but I can't see how removing the cable to clear the computer would help in a '94?

Can anyone give a straight and forward answer?

Mikado14 · #12 10-22-2004, 09:27 PM

Not being rude here but, can anyone explain why on a '94, disconnecting the battery cable causes the 4WD to correct itself?

Wanting to understand this, I looked at a schematic the other day and could only find a sensor that told the ABS when it was in 2WD or 4WD.

busa_4 · #13 10-23-2004, 05:23 PM

when you disconnect the power the computer has to relearn the sensor values.

Mikado14 · #14 10-24-2004, 12:41 PM

What sensors are there on a '94?

More problems. Cranked up the s-10 this weekend and pushed the 4high button for the heck of it and it went back to doing what it did before (blinking and not switching to 4x4). Put it in Neutral and the 4low works though. Didn't have time to try the battery trick again, but does this mean I have a short or something somewhere that caused a reset or something of the sorts???
