1989 Chevrolet S-10 4X4 Blazer with 4.3L V6. Solved my problem with 4 wheel drive not engaging. Replaced vacuum swith on transfer case and electric vacuum switch on front axle and now 4 High and 4 Low will engage again. My problem now is this! My 2 Wheel drive and 4 High light will come on the floor panel but my Neutral and 4 Low light will not come on even though it engages just fine. I have taken the panel loose and checked the two panel connectors and checked all 6 bulbs and they look fine. What else is there to check?
