Truck goes crazy when key is out of the ignition, Instrument cluster goes on and off, beeps, ...but I don't think it's the actual instrument cluster.

[QUOTE="Evox, post: 1041493, member: 74754"] You and me both. I signed off on the $139 diagnostic fee. It was clear I only wanted them to diagnose the electrical problem and gave them all the details. I don't want to send my cluster off to be repaired, only to find that it was the PCM, and I don't want to order a PCM to find it was the cluster after all or some other component glitching. I hate throwing parts at a problem without a clear understanding of what the problem actually is. I had a cluster go out this isn't a cold solder joint problem where gauges or components are failing to energize due to cold breaks in the solder; it's the opposite. Something is causing the PCM and instrument cluster to energize when the truck is off. It could have been a cascade of problems originating with the faulty ignition switch. The constant erratic on and off from the faulty switch may have lead to some other component overheating and short. I don't know. I'm just documenting all my thoughts and observations along the way, hoping this thread helps someone in the future that experiences similar problems. [/QUOTE]
