Question about 2002 Pontiac Grand Am

1 Answer

I have a 2002 Grand Am the mornings or when the car has dash lights, radio, heater and windows will not work. After a half hour, less or more...sometimes just my dash lights and radio will kick on..then a little while longer and my radio and windows will start working. We have replaced the ignition switch and checked all fuses...Were getting ready to replace the ignition switch again..Does anyone have any ideas?
