Gauges are wacky

so on our 08 Denali our gauges are all way off. Almost pegged or past pegged. Sometimes they work perfect then not so much. Could a ground be dirty? I hate GM gauges lol.

It’s like this but all sensor gauges.

100 PSI sounds about right at 0 rpm

stepper motor is bad

But could I loose 4 stepper motors around the same time?

Yes, check your grounds. Especially firewall to motor. Highly doubt they all went bad at once, possible but highly doubtful.

Ok on grounds I know the one on the firewall, then the one coming from the battery

Is there more?

So today my wife told me she believes all but 1 gauge was correct. WTF I haven't messed with it lately.

change in the weather, maybe something has been wet and dried out, all the more reason to check grounds and connectors
