Dear Click and Clack,  
  
 I have a 1995 GMC Sierra SL, extended cab with a 5.0 litre engine that we purchased new. Recently, I tried engaging 4 wheel high. The light did not come on the floor shifter, and it did not sound or feel like it engaged. I tried 4 wheel low, and it worked. I checked all the fuses and they tested good. The fuse cover and the manual showed a transfer case fuse in position #2, but there was none. There are no contacts for the fuse in this position. I used 4 wheel high about a month ago without issue. Can you provide guidance on what I can look for next. We are taking a trip in the next couple of weeks, and need 4 wheel high. Thank you in advance and love your program.
