Question about 1999 Chevrolet K1500
Several things could cause
this since it is auto 4wd and controlled by a COMPUTER! Start the simplest, cheapest troubleshooting first; the electrical and computer system contact plugs and points.
1. it could be cracked solder connections inside the push button switch - try to re-solder or replace the switch.
2. possibly the encoder motor is bad. It is on the side of the Tcase and turns a shaft to shift the case. - try getting one from a scrapyard and swap it, much cheaper than new.
3. The computer module failed, or the contact from the plug to the plug pins is corroded. - first try to unplug and plug back in a few times to make a good contact. if that fails to work, get a used one from the scrapyard and swap it ($50 compared to a new one $500!) Get some cleaning\lube spray from Radio shack for computer terminals to keep from corroding.
4. It could be that you just have a bad connection in the 4wd wiring system. That was my case, it was just the plug connection at the computer module and has been working ever since, and now I have a spare computer module sitting on the workbench.
The computer module is the biggest pain to get to. It is buried in the dash behind the headlight and push button 4wd switch. Good luck!
