I've replaced broken vaccum line to actuator from the solenoid (above the vortec distributor). Indicator lights not working (2wd, 4wdH, 4wdL, or auto. How do I reset service 4WD indicator light? Any help would be appreciated.

Thanks

Which transfer case? 233 or 236? 3 buttons on dash or more?
To clear codes or reset try removing the fuse no 15.
But first you need to pull codes.
A 236 a good eng/trans capable scanner will pull codes.
On a 233 ground pin 13 to retrieve codes.
Does your indicater light come on for a bulb check when you first turn on key?
If not check fuses.
Post back code no.
And engine sise and mileage and transfer case type.

Not to hijack the thread, but I have a 2000 Chevy Blazer LT and it recently started giving me problems with the 4x4. I push the button for auto 4x4 or 4Hi and the lights flashes, but the 4wd doesn't engage. I was doing some research on here last night and am still stumped on this one.

PS mine has 4 buttons.

It would be less confusing if you would start a new tread.
But answer questions and check and do the things I outlined in upper post.
We need the code no and the transfer case type.
233 or 236 the tag is on back of transfer case.
