We have a 1996 GMC K1500 4x4 with push button 4x4. The truck will switch into N, 2H and 4L but not 4H. We changed the encoder motor with a spare but had no luck. I would like to test the switch. Can anyone give some advice. I would like a wire diagram or something. Thanks for your help.
1996 GM K1500 no 4x4 High.?
