Question about Chevrolet S 10
I have checked everything and replaced vacuum lines and actuator cable and the vacuum switch on the transfer case, i can hear the encoder motor running and the tccm clicking when i hit the butons on the dash and te just blink twice and go out. i checked the codes using data link pin 13 and only came up with a code 1, what else could it be? i believe it to be the tccm

Before changing the actuator check the vacuum lines at the vacuum switch on the left side of the transer case if they are wet with transmission fluid the the switch is bad and that will prevent 4wd from engaging.

SOURCE: 95 Blazer 4X4 Problem
Ok I just got my 4x4 working again. I got it to work by taking out the 4wd, brake, and I believe the ctsy fuses for about one minute each and put them back in and now my 4x4 works like it used to. If that works for anyone else great, but if not then good luck finding a better solution to the 4x4 problem.

THE 4WD SWITCH IS A PROBLEM. ALSO THE GROUND CONNECTOR ON THE FRAME CLOSE TO THE DRIVERS DOOR IS A PROBLEM. IT USUALLY HAS A COATING OF THE UNDERCOAT MATERIAL ON THE FRAME THAT IS NOT REMOVED BEFORE THE CONNECTORS ARE PUT IN PLACE.
THERE ARE 2 BOLTS THERE THE OTHER IS AN ABS GROUND CLEAN OFF THE UNDERCOATING FIRST, PUT DIELECTRIC GREASE ON THE CONNECTION POINTS, THEN COVER THEM IN SPRAY ON UNDERCOATING. THIS IS A CHEAP FIX TRY IT FIRST.
RATE ME PLEASE.

after looking at the schematics for this vehicle, I can say with great certainty that you might have something wrong in your front axle on a straight axle model that wont let the servo engage the front axle. Now if you have independant front suspension, then where the servo motor goes into the transfer case could be the problem. pull the servo motor from the case/axle and look at the engaging mechanism. You are looking for worn parts that could cause binding or broken parts. This servo motor gets its command voltage from the ecm. The signal for the ecm generates from the transmission and your in cab switch. If you can hear the motor trying to engage, then all the other factors are working up to the motor arm. The light is just a by product of the ecm trying to engage the front axle
