Where are the wires located for the 4 wheel drive on a 2003 chevy s10?

SOURCE: Engine Wire diagram for S10

go to autozone.com and you can register any type car and they have pretty good prints and service manuals on line. I have an 89 chevy s10 I just rebuilt my motor and overhauled the complete truck just waiting on a new paint job. best of luck

There is a vaccuum operated switch located on the transfer case that sends vaccum to the accuator that pulls a cable that locks the front end in. Check for vac coming in and out of this switch if no vac out replace it. This switch is a very common problem. You can find them at most parts stores in the help section #49315. please rate.

the popping sound is the stabilizer links or the lower control arm bushings you can replace all bushings and both link kits for around 50.00 and the light is prob from the sensor on the transfer case or the front end i would remove and clean with dawn dishwashing liquid and put them back.
