You have a 1986 S-10 Blazer the four wheel drive shifts from 2 hi to 4 hi but the front diff does not lock in It will also shift into 4 low but the front diff still won't lock in why won't it lock?

Should have some kind of a synchronized solenoid to engage the front diff. go to a parts store to look at a wiring diagram to trace it down or stop in and ask about it at a dealer. they will usually help if they are not too busy. The above isn't entirely true. on a 1986 S-10 Blazer the front hubs are actuated via a vacuum system. Under the hood of the s-10 will be a black plastic ball. (A little bit bigger than a softball.) There should be a single vacuum line hooked to it. This is what causes the front hubs to lock.

Never heard of a "front wheel modulator" on a S-10 Blazer. If you mean hub, it is the wheel bearing assembly. If you meant 4x4 shift solenoid then depends if it is shift on the fly or not. The ABS has a modulator, but not sure what you mean.
