Having problems with your 2000 Chevrolet S-10 ?
2000 S-10 wont lock into 4-wheel - 2000 Chevrolet S-10
If you live where it is very cold could be a chance of moisture freezing in the vapor line that engages the 4wd .... I burnt out a 1998 s10 blazer like this living in the mountains of Colorado one winter season. Try parking it in a heated garage and see if this seems to solve the engagement issue.
