I have boost and water temp gauges mounted in a pod on the A pillar. Problem is they both just stopped working. They have power, light up, but don't register anything.

Any ideas?

 

Gonna need some more info on this one. If they went out at the same time, what do they share? Chances are two unrelated systems aren't going to fail at the same time. Trace it back to their common component and check that.
