My 2001 Town Car has an issue with the instrument cluster & digital display intermittently will flat line & all warning lights, ABS, brake, air bag, service engine soon illuminate and the speedometer, overdrive, &traction control don't work!!!!!!!!! I have had it in the automotive electrical shop diagnosed as defective cluster. I paid for r&r of cluster with used one reprogrammed security system and scan for codes, still problem is not fixed or diagnosed !!! And I have forked out Hundreds of dollars!!!!!!!!
