Like the title says. I turn the blower motor in the cabin to speed 3/4 the speedometer drops out. At speed 4 the other gauges will also drop out and come back at random. This happened after I tore apart and put back together the dash to replace the heater core. Odd thing is this issue only started a few weeks after that project.
I know its a wiring harness, ground issue, fuse box, or broken wire somewhere. I'm really just asking where I should start diagnosing the cause of the issue.
