Welcome Aboard!
Sorry for the slow response.
The two problems may be related, or may be coincidental. Both get their power through the GAGE fuse, but so do several other devices. Both are also connected through the instrument panel backplane connectors, and those can work loose over time, especially on an older or higher mileage vehicle.
The IP trim bezel can be unsnapped from the dash, and the IP can be removed and the connectors cleaned and inspected fairly easily.
