The problem is getting more common and I haven't been able to track it down. Sometimes when I turn my 03 f250 7.3 the radio, cd, or tape deck doesn't work. the clock doesn't light up unless I turn my lights on. I have tried to jog the gear selector lever (automatic), turned the truck off and on, jogged the ignition switch and no luck. Then I will be driving down the road and it will come on. Any ideas will be appreciated.
