Gauges 03 Silverado quit working when there is moisture in air

This is a really common problem on all the 03-06 Silverados and is usually due to cracked solder joints inside the gauge cluster. The temperature change is enough to make the tiny solder crack (so thin it's almost invisible) open up and close back up causing intermittent problems and complete power failure like you are having. The good news is it's definitely fixable and I've personally fixed many, many with this exact issue.
