Okay, so what needs to happen here is to find out where the short to ground is in the circuit. Usually these happen somewhere in the instrument panel itself, but not always. To do the diagnostic though, the instrument panel is going to have to be removed anyway to get at the electrical connectors to run some tests on them, so either way the instrument panel will need to be removed. In the diagrams down below I have included the instructions on how to remove and install the instrument cluster on your vehicle. Please remove the instrument cluster from your vehicle and then take a voltage reading of pin 2 of connector 256 with the black lead of your Digital Multi-meter[DMM] touching a good ground. I have also included diagrams of the three electrical connectors going to the instrument cluster with callouts in the diagrams down below as well. If you are unfamiliar with how to use a DMM, here is a link below explaining how to use one, if needed:
Please take this voltage reading and report back here with the results.
