when driving on bumpy road all warning pop on and gauges go to zero readings. checked all fuses in the main fuse box which are okay andthen press box down and all warning lights go out and gauges are working until I drive on a bumpy highway again
All warning lights come when driving on bumpy road on 2000 Saturn LS2
evidently you answered your on question. have an ASE technician to repair or replace the fuse box.
