Need help here. Does anyone know of a way to resart, or maybe reboot a computer, on a 2003 sierra 1500? Symptoms: Radio stays on after door open and key are out of ignition.Four wheel drive would'nt disingauge until truck was shut off then restarted. Windsheild wipers studder every third or fourth swipe.

 

unhook the battery for a few mins and hook it back up.

 

Dont you turn the key to till the lights come on and press youre gas peddle all the way to the floor 5 times kind of quickly
