electrical problem with my 2004 GMC SAVANNA 2500
WHEN I START TO DRIVE,THE INSTRUMENT CLUSTER GOES DEAD AND THE LOW/HIGH BEAM HEADLIGHTS QUICKLY BLOW OUT SOON AFTER.ALSO,WHEN I STOP AT A LIGHT,THE TRANSMISSION SEEMS LIKE ITS IN A ODD GEAR TO START OR SOMETIMES MAYBE NEUTRAL.CAN HEAR WHAT SEEMS TO BE A RELAY CLICKING ON THE PASSENGER SIDE FIREWALL.WHEN STOPPED AT A LIGHT,THE INSTRUMENT CLUSTER COMES BACK ON,BUT THE VOLTAGE GUAGE READS TOO HIGH AS YOU START TO MOVE.....BAD GROUND?BAD FUSE?SHORT?....ANY HELP IN THE RIGHT DIRECTION WOULD BE MUCH APPRECIATED...
it sounds like your dash boared is bad.also try changing your neutral safety switch it goes on the side of your transmission.
