I own a 2008 silverado that I bought new before the bailout and everything at chevy was being given away. My problem is intermittent and seems to fix itself, I have had the a/c not work abs lights flash,power door locks fluctuate and all that while driving. When it is parked I will unlock it using the key fob everything will light up truck will unlock get put key in the ignition to start and everything will shut off. It is as if someone took out the battery, I have no horn no 4ways no power of any kind. Now it does not do this all the time but is happening more frequently. Last time I took it to the dealer the tech told me it fixed itself he dont know what he did,but told me to get rid of it as soon as possible. That was while it was under warranty now it will cost me a small fortune for them to tell to get rid of it.
