Hi Sam. There are a few places the actual buzzer will be. Its either in near the fuse panel or under the dash on the drivers side. Since this is a 97 it is hard to say if the factory one or an aftermarket is installed. Some of the trucks went with a module assembly that ties in with the low air light and kyser warning system in the overhead consoles. Click on this link below for the diagram. Yours likely burnt out part of the circuit board. Your option is to replace it or wire in an aftermarket buzzer into the pressure switch and circuit. Let me know
