Woke up to a dead battery. Jumped it and found the accessory gauges not working. Also the power window switch’s on the drivers door don’t work. Power side mirror does work. ABS and battery light are on. Radio does not have any volume as well.

Welcome to 2CarPros.

The first thing to check is the battery itself. If the battery is weak and the alternator isn't working, all kinds of electrical issues can occur.

Here are a few links. I need you to follow them and do some basic testing.

First, check the battery. (link 1)

If it checks good, I need you to check the alternator. Follow link 2. This requires the use of a volt meter or a multi meter.

Also, make sure the battery terminals are clean and tight.
