Did you pull the cluster out at any point before the temp gauge went bonkers? Maybe a wire got pinched or something?

Did someone install an alarm system or some sort of accessory lately?

I didn't use the Ultra-Gauge windshield mount...I made my own from a wire hanger, a screw and washer. I guess you could use the factory screw fer the cluster if you don't want to put a hole in yers... <img src="/forums/images/graemlins/wink.gif" alt="" />
