I just recently parked my Chevy 1500 Silverado WT to do some routine work. when I attempted to start it up all that happened was the key turned and the instrument panel lights went out and there was an audible click from that area. I got out and check the battery connections, battery (which is fairly new) and the starter relay on the fuse block. I even tried jumping it off of a running vehicle, but still the same problem exist. All the lights and radio work fine so I assume the battery is not the cause for the sudden death. I tried swapping the starter relay with another relay (one that was for fog lights which I don't have) and I still get the same response. I then took out the ignition relay fuse and found the power side and connected it to the ground terminal and nothing happened. I repeated the same steps on the starter relay and I heard the starter click. I have never had any starting problems (with the exception of the key getting stuck from time to time) with the truck or any kind of work done recently. I don't have a anti-theft system as far as I know. Since I'm sure the problem is electrical in nature could anyone tell me what could be the cause or what I should investigate next? I understand there could be many failures in the system that could cause this, so I will try and seek out the most likely causes first. Hopefully I can avoid having to tow it to the dealer for a diagnosis and repair with the help of a knowledgeable and friendly mechanic. Thanks in advanced for anyone who can help me.

I had a strange problem with my '03 GMC Sierra but was able to figure it out and thought I'd post a summary in case someone else can benefit from it. The symptoms were random and odd. The ABS/Brake dash lights would come on every couple weeks and the chime would go off a million times, then started happening more often and finally started happening when I'd turn the key to the "on" position before starting the engine. I figured it had something to do with the ABS module maybe and would look into it, except that when it got really bad it was at the same time my A/C blower and electric windows wouldn't work. AND, the transmission would go into "limp mode" and stay in third gear. I figured it had to be related since it all started going bad within one day, then the truck wouldn't start at all, luckily in front of my house. I suspected the ignition switch since that's a place where multiple components are powered. I grabbed a good used switch (I work at a wrecking yard) and swapped it out and that didn't help so I checked power to the switch. One wire was hot going to the switch but when I rotated the wheel to acc and on positions only a ocuple wires lit up out of eight! Good switch but power not being distributed. Turns out that there's two power wires that go to the switch, in my case both red wires (some schematics show red and red/wht) and the other red wire was dead. I checked it at the fuse box and it had power, probed the wire from the fuse box to as far as I could toward the fire wall and had power, then started at the switch and probed the wire past the big connector under the dash as far back to the firewall as I could and it was good (continuity test). So I decided I had a bad power wire at the firewall somewhere. In my book this is weird, I've never had something like that happen before, but the bad wire was buried in the wire loom so much that I decided to cut the wire at both ends and solder a new "patch" in. Everything worked! The A/C and windows have worked perfectly for three weeks and the transmission never showed a problem again. The only disappointment has been the ABS/Brake lights lighting up once in the past three weeks. Not sure what to think about that yet. Sorry for the long explanation but I think it's all important. Hopefully no one else ever has this problem... Dan

The New York Times reported today that this is one of the six bellwether cases being tried to determine how a settlement or class action trial might proceed. GM commented on the case in a statement, saying “The jurors studied the merits of the case and saw the truth. This was a very minor accident that had absolutely nothing to do with the car’s ignition switch.” Read about the prior case here. Graphic courtesy of GM

ABC News reports that "...Scheuer, a mail man, had a two-decade history of surgeries and pain medication prescriptions for spinal issues. He also said two calls to Scheuer's cellphone messaging system from his phone contradict his claims he was unconscious for three hours after the accident." Mr. Scheure's lawyers did not dispute the claim by GM. Background story - GM Ignition Switch Defect Hurt Or Killed 400 Image of GM's Mary Barra is from her testimony on the issue to Congress.

Second, Nobody at General Motors will be charged with a crime. Like the similar Toyota settlement, the charges will be deferred. GM simply has to not do this type of thing again, and nobody will be held responsible. According to AP, the crimes its employees could have been charged with are "... wire fraud and scheming to conceal material facts from a government regulator." Last, GM will pay $900 million to the U.S. government in a penalty about 30% lower than that which Toyota paid. The penalty represents less than 2% of the tax payment deferrals the company was allowed to keep as part of its 2009 bankruptcy and less than a tenth of the direct cost of the bailout paid for by the U.S. taxpayers.
