When i engage the 4 wheel drive it wont engage the front wheels. Does the actuator have anything to do with that or can there be another problem why its not engagaing?

What is your question?

I have a 4.3l v6. The 4wheel drive isn't working.

What makes this problem better or worse?

Nothing it just doesn't work.

How long has your 1991 Chevrolet S10 had this problem?

Probably scenes I bought it
