Hi and thank you for your question.
The first thing to check would be the fuses. Pull each one out and inspect it. Most of the time, but not always, you can see a blown fuse. Sometimes you cannot. If you don't see any obvious signs of the fuses having blown, either replace them with new ones, or check them with an ohm meter.
Give that a shot and let me know if you need more help.
