I am having two electrical issues with my 2015 Yukon XL Denali

First - today the speedometer and tachometer stopped working on the instrument cluster. The HUD still registers speed but the needles on the dials stay at zero. I checked fuse #25 on the left fuse panel since it made the most sense. The fuse was fine.

Second - the driver side heated seat is not working. The indicator light illuminates when engaged but the seat does not heat up. The fan for cooled seat does come on and the associated fuse is fine. The fuse is for both heat and A/C.

I appreciate any assistance.
