I need help! I have a 1999 C3500 6.5 turbo, manual transmission and the gauge fuse is blowing a few seconds after turning the switch on. I have been through the threads on here troubleshooting it. So far I have disconnected the glow plug controller, fuel heater, WIF sensor, ECT on the cross over, cruise control, and rear window defogger. I disconnected each and tested separately as well as removing the cluster and trying without it. The fuse still blows, but if I connect the block warmer and let the engine warm up all is well. So I know it's in the cold start circuit. Is there anything I'm missing? Please help.
