how is your windsheild? This era of truck (pretty sure it included the 97correct me if i'm wrong) tended to leak a little, drip down onto the GEM (generic electronic module) and funny stuff starts to happen. A popular one is the electroic shifter goes ka-plat or will work once in a blue moon, such as go into 4 high but not back out. The GEM is located in the dash above the fuse panel. Check the surrounding metal for signs of rust= possible moisture.
