why won't my car work in accessory mode? on 2002 Buick LeSabre
First check all the fuses. If all fuses are good it is most likely the ignition switch.
If all systems work normally in the 'run' position just not the 'acc' position then it's NOT fuses , it'sa power distribution issue which as 'chevy power' says would most likely be a faulty contact in the ignition switch/circuit. What methods do you have available to test with , before your 'hot date' , so it doesn't turn into a 'not date'?
