Does anybody have the wiring schematic for the overhead console for a 1990 Cherokee? My compass and temp come on and off randomly, so there has to be a power or ground issue. Either that or the RENIX ghost that lives back by the spare tire is restless... Need to know where the wiring and grounds run. Or a good exorcist...

Yeah... Been one of them days...

 

Or your compass/temperature module is going out. It is twenty two years old. You would have to trace the harness down to under the dash.
