My mother inlaw ownes a 2003 Grand-am. Lately when you start the car, the engine fires right up but nothing else inside the car comes on. No power windows, dash, ac, nothing. Some times when you restart it they all come on. Anyone know where I should start troubleshooting? I sprayed some lube into the ignition switch, no change.
drop the column covers and follow the wires from the key switch all the way down to the BCM. Somethin's up between the two.
