The blower motor resistor module is ruined and need replacement. It can be found from below and behind the glove box. Tt may be hard to see, follow the wires to connection that is mounted to the blower unit by two small hex-head screws. I removed the glove box so I could access it easier than trying to go from the bottom in a confined position.

Why the Blower motor not work on high speed on a jimmy 97?
If the blower works on slower speeds only I would suspect the high speed blower motor relay (under the hood in the power distribution box) or the switch itself. The blower speed resistor is working if all the slower speeds work.
