So, here's a good one: My temperature gauge is toast. It shoots STRAIGHT up to the top of the meter while the car is warming up, and then goes to it's normal place afterwards. I've diagnosed it down to a diode on the meter ... and it'd be rad if I could just replace it... but there's many different complications there. So, I know the part number (78130-S04-941) But... it's discontinued. How would ya'll go about finding a part like this?
