    Overheating?

    So... any idea on why my temperature gauge is spazzing? I don't think my car is overheating. I've shut off the car after it spazzing and it sits at the normal temp once I've turned it back on.

    Hope the videos help:

    That could be a bad connection where the gauge mount to the PCB in the cluster. Tightening the nut may help, but the real fix is to disassemble the cluster and re-flow solder on the pad. Do the same for the fuel gauge.

      Also check your SI board/batteries after you pull the cluster.

        I confirm both of these suggestions. I have fresh SI board batteries on the way so if you need a replacement SI board or wanna have your batteries replaced, which I know you will, let me know. PM me.

        Another troublesome fix for gauges acting erratic is the grounding lugs mounted above the brake pedal. They get corroded and cause all kinds of cluster problems.

        In your case, SI batteries or grounding nut is surely the problem.

          I'll look into both of those fixes.
