I know a lot of you guys are driving Chevy trucks, have any of you had electrical problems ? The truck will act like the battery is dead,then start up like nothing is wrong. While driving down the road the gauges will go haywire, elect locks start going up and down,radio goes out then it shuts down. If anybody else has had similar problems....what was the fix?? The dealership guys act like they have never heard of this problem!
Did you buy the truck new? Has it ever been flooded?
sounds like your loseing ground at times
Truck never flooded, it started out with the starting problem . The elect locks and shutting down just started this week, the ground issue could be the deal.

About made a ghost out of me when it stalled out pulling into traffic Monday !
My son's 08 did that. We unhooked the battery then separated the harness from the fuse box and cleaned it with ether. Make sure to unhook the hot post first or you can fry the harness. There are 2 twist style connectors there. His dash was going in and out randomly. Like you, the service techs just stared at us like we had a flipper growing out of our head when we asked. The famous "never heard of that before". Told me they would just start replacing modules until it started working again. Y'all may have better service over that way. Hasn't done it again in a couple of months. Good luck!
If you have a friend with a sensor id You may be able to identify the problem. The hand held unit that plugs in under the steering wheel. The parts houses here will let you borrow one for a few minutes to get the fail codes
Alternator maybe?? Last time mine would not crank every time it rained... Weird.. Finally had a guy climb under there and tap the starter with a hammer and identified the problem.
Not an 08, but my 03's dash gauges have been off for a while and the radio was the 1st to go. Ended up just pulling the fuse for the radio. Speedometer, oil pressure, tachometer, work when they want to. Fuel, voltage, temperature have not been affected. Ran the codes down, but found nothing. Was told by GM tech that it was a normal wire harness in dash that needs replaced which was a "known" problem. Been doing it for years, but not affected starting or running. Just not spent the $$ yet to replace the harness. Check the oil regularly and GPS speed helps keep me from getting a ticket. Will try cleaning the harness connection at the fuse box mentioned above to see how that works for me.
Had one do the EXACT same thing...believe it or not... It was the battery. Had a cell loose inside it is what I was told. Put a new one in it and everything went back to normal.
2001 GMC I tear into the steering wheel to get to the horn points. Sand them down for 1 blow when it goes through inspection. It won't blow the second time.
Radio will not stay on selected stations, it's off most of the time.
had the same problem !!! once the battery was replaced no more issues !!!Quote:
