DC switches not functioning

Hello there, I’ve purchased a 2019 29CB. VERY HAPPY. The boat is five years old and has been sitting, and so some items are not functioning as they should. The three DC breaker switches to the left of the winless, for example. O/H fan, macerator and remote for the thrusters. Is there a blade fuse that I need to find? I’ve looked around, I’ve looked at the manual and can’t find anything. Any help truly appreciated thank you.

There is a 30 amp fuse for that 4 button switch panel. Its located behind the dash.

Found it ! Great. What about the same for the rear deck lighting. ? The switch is at the upper helm and then there are three switches in the rear cockpit for red lights / white lights and also intensity. These work but the fuse trips after thirty seconds.

The fuse block for that panel is located under the CB bridge, directly below the VHF mic mount. It’s possible that one of the lights has failed and is causing the fuse to blow. I would remove the lights and the switch panel and check for corrosion.
