tonight i was driving and all of a sudden i lost half of my dash the tach left turn signal and water temp and volts the vent back to zero if i pushed the dash down lightly they came back on wondering if its a wire or my instruments?

 

it could be either or both, you'll have to figure it out yourself. It's not really something you can just diagnose like that, you'll have to try wiggling the wires under the dash until you find the one thats loose. I could be wrong maybe someone knows what it could be however.
