CHEVY 4WHEEL DRIVE

1995 Chevrolet Silverado

Transmission problem
1995 Chevy Silverado V8 Four Wheel Drive Automatic

Hello, I own a 95 silverado and recently came to find out that my 4 wheel drive is not working, not only did the light not get lit but there wasn't any pull from the front wheels at all, I have a Haynes/Chiltons repair manual for it but it doesn't troubleshoot or explain the 4 wheel drive in it, I'd thought that it was controlled by vacume pressure but I really don't know.I've had 4 wheel drive in the past but not now. Any help?Thanks.

There is a electric actuator in the front differential that needs 12v when 4wd is activated. If it has power then the actuator is bad. They are very common for failing

Hello again, I replaced the thermal 4x4 acuator with an upgraded electrical 1 but it says to splice this brown wire from the new acuator into a brown wire on the 4 plug wire of the trans case, there is no brown wire and I believe it may be the black and grey wire, any suggestions?I need my 4x4 working again and from what I gather the factory acuators go bad frequently so thats why I upgraded, now it needs to be completed. Thanks.
