there is a vacum actuator located on the passenger side of the vehicle.checck the vacum hose to make sure it is getting vacum when you enguage the switch or gear shifter.this has a cable that goes to the front difererential that acuates to engage the front diferential.the vacume hose may come loose.or the cable pulled out of the holder that connects to the acuator.

My 93 blazer has a vacum line behind the intake in front of the dis. it fell apart 4X4 stopped working i just replaced it it worked great 1993 4.3W

A 4WD on a 2001 Chevy S10 Blazer does not work properly after changing its actuator and speed sensor probably due to shorted wires. Also check for loose wiring.Ê

Yes, you can put a 1998 4WD S10 drive-train on a 1997 Chevy Blazer. However, it will not be an easy process and will require a lot of work to get it installed correctly.

You don't. You sell the 4wd to a person who wants it and buy something else!!!
