Okay, so we took the truck to church this morning. No issues on the drive over. When we left, I noticed that the speedometer wasn't working. Or the tachometer. Or the odometer!! I pushed the overdrive button...nothing. It won't shift inot overdrive, and I've got no gauges. All the other gauges work: oil pressure, fuel gauge, temp, ect. Just no speed, tach or odometer. I checked all my fuses, nothing there.
What gives!!!??!!! I'm about ready to call it quits with this truck and get a new one!!
I say stop going to church!!!
JK... check the grounds at the batteries, then the wires at the heater grid, and then the relays for the heaters, if it's not that... try the wires that feed the power center under the hood. Most times an electrical issue is a bad sensor or a bad ground. Good luck... Chris
I know it sounds dumb, but if you have the trailer light kit with the seven prong plug, unplug the harness that feeds it and see if it helps. I had a real tough time with my bud's truck until I replaced that and it cleared up all kinds of Gremlins. Remember to use di-electric silicone on all the connectors to keep it from happening again... Chris
