First check all the fuses. If all fuses are good it is most likely the ignition switch. - Chevy Power
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'? - ziptie12
