This would be your "Body Control Module" giving you these problems. But you'll have to probe the wiring and connectors to isolate the problem.
If you'd like to tackle this yourself, you should purchase a "Single Vehicle" subscription to an on-line service such as AllData, or Mitchell 1. This will give you your wiring diagrams and specs to guide you, as well as come in handy on your next project.
