Gauges, window and locks not working

I have the truck listed above it has been sitting for a couple months. Battery was dead had to jump start it. As we were trying to jump start it gauges would go up sometimes but once we got it started rpm's and speedometer are the only gauges that work. Can't see if I'm in park or drive. Battery light is on along with ABS and engine. Scanner won't connect. Some light doesn't work, no ding from the key, windows don't work and now won't lock. Dash lights do work and radio works and the truck runs fine.
